GLSL 1.50 and GLSL 4.40 specs, they both say the same in
"Interface Blocks" section:
"If optional qualifiers are used, they can include interpolation qualifiers,
auxiliary storage qualifiers, and storage qualifiers and they must declare
an input, output, or uniform member consistent with the interface qualifier
of the block"
From GLSL ES 3.0, chapter 4.3.7 "Interface Blocks", page 38:
"GLSL ES 3.0 does not support interface blocks for shader inputs or outputs."
and from GLSL ES 3.0, chapter 4.6.1 "The invariant qualifier", page 52.
"Only variables output from a shader can be candidates for invariance."
This patch fixes the following dEQP tests:
dEQP-GLES3.functional.shaders.declarations.invalid_declarations.invariant_uniform_block_2_vertex
dEQP-GLES3.functional.shaders.declarations.invalid_declarations.invariant_uniform_block_2_fragment

This lets us be slightly more efficient by not walking the CFG extra times.
Also, it may make it easier to ensure that GVN happens on only unpinned

Right now, the nir_instr_prev function function blindly looks up the
previous element in the exec list and casts it to an instruction even if
it's the tail sentinel. The next commit will change this to return null if
it's the first instruction. Making this change first avoids getting a
segfault between commits. The only reason we never noticed is that, thanks
to the way things are laid out in nir_block, the casted instruction's type
was never parallal_copy.

Previously, if you remved a CF node that still had instructions in it, none
of the use/def information from those instructions would get cleaned up.
Also, we weren't removing if statements from the if_uses of the
corresponding register or SSA def. This commit fixes both of these
problems

This is mostly thanks to Connor. The idea is to do a depth-first search
that computes pre and post indices for all the blocks. We can then figure
out if one block dominates another in constant time by two simple
comparison operations.

Being able to find the least common anscestor in the dominance tree is a
useful thing that we may want to do in other passes. In particular, we
need it for GCM.

Create a new search function to look for matching built-in functions by name
and use it for built-in function redefinition or overload in GLSL ES 3.00.
GLSL ES 3.0 spec, chapter 6.1 "Function Definitions", page 71
"A shader cannot redefine or overload built-in functions."
While in GLSL ES 1.0 specification, chapter 8 "Built-in Functions"
"User code can overload the built-in functions but cannot redefine them."
So this check is specific to GLSL ES 3.00.
This patch fixes the following dEQP tests:
dEQP-GLES3.functional.shaders.functions.invalid.overload_builtin_function_vertex

v2: Rebase on the nir_opcodes.h python code generation support.
v3: Use SSA values, and set an appropriate writemask on dot products.
v4: Make the arguments be SSA references as well. This lets you stack up
expressions in the arguments of other expressions, at the cost of
having to insert a fmov/imov if you want to swizzle. Also, add
the generated file to NIR_GENERATED_FILES.
v5: Use more pythonish style for iterating the list.
v6: Infer the size of the dest from the size of the srcs, and auto-swizzle
a single small src out to the appropriate size.
v7: Add little helpers for initializing the struct, add a typedef for the
struct like other nir types have.

Add a enter/leave record callback so that the offset may be aligned to
the proper value. Otherwise only leaf fields are called, and the first
field needs to be aligned to the outer struct's base alignment while the
last field needs to be aligned to the inner struct's base alignment.
This removes most usage of the last field/record type values passed into
visit_field.
