ccbb52ac11 glsl: fix check SSBOs support for builtin functions
has_shader_storage_buffer_objects() returns true also if the OpenGL
context is 4.30 or ES 3.1.

Previously, we were saying that all atomic*() GLSL builtin functions
for SSBOs were not available when OpenGL ES 3.1 context was in use.

Fixes 48 dEQP-GLES31 tests:

dEQP-GLES31.functional.ssbo.atomic.*

c8f5274b52 nir: Get the number of SSBOs and UBOs right
Before d31f98a272 and 56e2bdbca3 we had a sigle index space for UBOs
and SSBOs, so NumBufferInterfaceBlocks would contain the combined number of
blocks, not just one kind. This means that for shader programs using both
UBOs and SSBOs, we were setting num_ssbos and num_ubos to a larger number than
we should. Since the above commits  we have separate index spaces for each
so we can just get the right numbers.

2d7a98de18 glsl: add AoA support for atomic counters
This marks all counters in an AoA as active.

For AoA all but the innermost array are treated as separate
counters/uniforms. The Nvidia binary also goes further and
finds inactive counters in the AoA, in future we should do
this too, however this gets things working for the time being.

This change also removes the use of UniformHash for atomic counters,
this avoids having to generate name strings used as hash keys.

410609c968 glsl: remove dead code in a single pass
Currently only one ir assignment is removed for each var in a single
dead code optimisation pass. This means if a var has more than one
assignment, then it requires all the glsl optimisations to be run again
for each additional assignment to be removed.
Another pass is also required to remove the variable itself.

With this change all assignments and the variable are removed in a single
pass.

Some of the arrays of arrays conformance tests that were looping
through 8 dimensions ended up with a var with hundreds of assignments.

This change helps ES31-CTS.arrays_of_arrays.InteractionFunctionCalls1
go from around 3 min 20 sec -> 2 min

ES31-CTS.arrays_of_arrays.InteractionFunctionCalls2 went from
around 9 min 20 sec to 7 min 30 sec

I had difficulty getting the public shader-db to give a consistent result
with or without this change but the results seemed unchanged at between
15-20 seconds.

Thomas Helland measured change with shader-db on his machine from
approx 117 secs to 112 secs.

V3: Simplify freeing of list as suggested by Ian, and spelling fixes.

V2: Add assert to be sure references are counted before assignments.

db280e951a glsl: Add support for linking uniform arrays of arrays
V3: Fix setting of data.location for struct AoA UBO members

V2: Handle arrays of arrays in the same way structures are handled

The ARB_arrays_of_arrays spec doesn't give very many details on how
AoA uniforms are intended to be implemented. However in the
ARB_program_interface_query spec there are details that show AoA are
intended to be handled in a similar way to structs.

Issues 7 from the ARB_program_interface_query spec:

 We define rules consistent with our enumeration rules for
 other complex types.  For existing one-dimensional arrays, we enumerate
 a single entry if the array is an array of basic types, or separate
 entries for each array element if the array is an array of structures.
 We follow similar rules here.  For a uniform array such as:

   uniform vec4 a[5][4][3];

 we enumerate twenty different entries ("a[0][0][0]" through
 "a[4][3][0]"), each of which is treated as an array with three elements.
 This is morally equivalent to what you'd get if you worked around the
 limitation in current GLSL via:

    struct ArrayBottom { vec4 c[3]; };
    struct ArrayMid    { ArrayBottom b[3]; };
    uniform ArrayMid   a[5];

 which would enumerate "a[0].b[0].c[0]" through "a[4].b[3].c[0]".

9de651b261 glsl: Fix variable_referenced() for vector_{extract,insert} expressions
We get these when we operate on vector variables with array accessors
(i.e. things like a[0] where 'a' is a vec4). When we call variable_referenced()
on these expressions we want to return a reference to 'a' instead of NULL.

This fixes a problem where we pass a[0] as the first argument to an atomic
SSBO function that expects a buffer variable. In order to check this, we use
variable_referenced(), but that is currently returning NULL in this case, since
the underlying rvalue is a vector_extract expression.

6a506689db glsl: fix matrix stride calculation for std430's row_major matrices with two columns
This is the result of applying several rules:

From OpenGL 4.3 spec, section 7.6.2.2 "Standard Uniform Block Layout":

"2. If the member is a two- or four-component vector with components
consuming N basic machine units, the base alignment is 2N or 4N,
respectively."
[...]
"4. If the member is an array of scalars or vectors, the base alignment
and array stride are set to match the base alignment of a single array
element, according to rules (1), (2), and (3), and rounded up to the
base alignment of a vec4."
[...]
"7. If the member is a row-major matrix with C columns and R rows, the
matrix is stored identically to an array of R row vectors with C
components each, according to rule (4)."
[...]
"When using the std430 storage layout, shader storage blocks will be
laid out in buffer storage identically to uniform and shader storage
blocks using the std140 layout, except that the base alignment and
stride of arrays of scalars and vectors in rule 4 and of structures in
rule 9 are not rounded up a multiple of the base alignment of a vec4."

In summary: vec2 has a base alignment of 2*N, a row-major mat2xY is
stored like an array of Y row vectors with 2 components each. Because
of std430 storage layout, the base alignment of the array of vectors
is not rounded up to vec4, so it is still 2*N.

43b07eb60f glsl: Allow built-in functions as constant expressions in OpenGL ES 1.00
In d4a24745 (August 2012), Paul made functions calls not be constant
expressions in GLSL ES 1.00.  Since this feature was added in desktop
GLSL 1.20, we believed that it was added in GLSL ES 3.00.  That turns
out to be completely wrong.  Built-in functions have always been allowed
as constant expressions in GLSL ES, and the patch adds the (many) spec
quotations to prove it.

While we never previously encountered this, a later patch enforces a GLSL
ES 1.00 rule that global variable initializers must be constant
expressions.  Without this fix, several dEQP tests fail.

Fixes:

Yes, I know we don't maintain stable branches that far back, but that
*is* how far back this bug goes!

7a1143f29e glsl: include variable name in error messages about initializers
Also fix style / wrong indentation along the way and make the messages
more uniform.

f09c229cc6 glsl: shader outputs cannot have initializers
GLSL Spec 4.20.8, 4.3 Storage Qualifiers:

"Initializers in global declarations may only be used in declarations of
 global variables with no storage qualifier, with a const qualifier or
 with a uniform qualifier."

We do this for input variables, but not for output variables. AMD and NVIDIA
proprietary drivers don't allow this either.

c9b982b72d glsl: move shader_enums into nir
First step towards inverting the dependency between glsl and nir (so nir
can be used without glsl).  Also solves this issue with 'make distclean'

bb59ba8634 nir/instr_set: remove unnecessary check in nir_instrs_equal()
This was originally added to nir_instrs_equal() instead of
nir_instr_can_cse() incorrectly, but this was fixed when moving to the
instruction set API (as it had to be, otherwise hashing wouldn't work).
Now, this is dead code since instr_can_rewrite() will only return true
for texture instructions that use an index, so we can turn the check into
an assert. This also means that now nir_instrs_equal(instr, instr) will
always return true unless it assert-fails.

bf5f931aee nir: make nir_instrs_equal() static
This was previously tied to CSE, since it would only work for
instructions where nir_can_cse() (now instr_can_rewrite()) returned
true. Now that CSE uses the instruction set abstraction which only uses
this internally, we can make it local to nir_instr_set.c.

e8308d0523 nir/cse: use the instruction set API
This replaces an O(n^2) algorithm with an O(n) one, while allowing us to
import most of the infrastructure required for GVN. The idea is to walk
the dominance tree depth-first, similar when converting to SSA, and
remove the instructions from the set when we're done visiting the
sub-tree of the dominance tree so that the only instructions in the set
are the instructions that dominate the current block.

No piglit regressions. No shader-db changes.

Compilation time for full shader-db:

Difference at 95.0% confidence
        -35.826 +/- 2.16018
        -6.2852% +/- 0.378975%
        (Student's t, pooled s = 3.37504)

v2:
- rebase on start_block removal
- remove useless state struct
- change commit message
