Instead of passing s,t,r coordinates pass a coord array - the reason is that
I need to pass more coords (in particular for shadow "coord", future will also
need another one for cube map arrays) so just pass them as an array.
Also, to simplify things, use fixed location for the shadow reference value I
want to get rid of the silly "where is the right coord value" game.
Keep old-style however for aos sampling (which is not going to need shadow
coord, though for cube map arrays it still would need fixing).
(Next patch will pass those through using the new arrangement directly from
sampler interface.)

We need to put border color into texture format color space which
essentially means clamping for non-float, normalized formats (not entirely
sure if we're also meant to quantize the float but it's probably ok not to
do it thankfully).
For OpenGL we could do this easily outside generated code due to the
1:1 sampler/texture correspondence but not for d3d10 which is terrible
(as we recalculate a constant over and over again per shader invocation).
Fortunately border color should be rare enough that we don't care THAT much.

In commit 8fc41df (glsl: Modify ir_set_program_inouts to handle
geometry shaders), when attempting to pattern match the "foo" part of
expressions such as:
foo[i][j]
foo[i]
I incorrectly called as_dereference_variable() on the subexpression
foo[i] instead of foo. As a result, the pattern never matched, so
ir_set_program_inouts would fall back on marking the entire variable
as used, rather than just the portion indexed by the array.
This didn't result in incorrect behaviour, but it could have resulted
in inefficiency by causing the back-end to allocate resources for
unused parts of an input or output array.

Previously we would emit a warning for empty declarations like
float;
We would also emit the same warning for things like
highp float;
However, this second case is most likely the application trying to set
the default precision. This makes the compiler generate a stronger
warning with some suggestion of a fix.
It really seems like this should be an error. I'll bet that 100% of the
time someone writes 'highp float;' the actually meant 'precision highp
float;'. Alas, both AMD and NVIDIA accept this syntax, and the spec
doesn't explicitly forbid it.
This makes piglit's precision-05.vert generate the following warnings:
0:12(11): warning: empty declaration with precision qualifier, to set the default precision, use `precision lowp float;'
0:13(12): warning: empty declaration with precision qualifier, to set the default precision, use `precision mediump int;'

GLSL ES does not allow unsized arrays, and GLSL ES 1.00 does not allow
array initializers. However, GLSL ES 3.00 allows array initializers,
and the initializer can explicitly size the array. The specification
even includes some examples of this:
float x[] = float[2] (1.0, 2.0); // declares an array of size 2
float y[] = float[] (1.0, 2.0, 3.0); // declares an array of size 3
float a[5];
float b[] = a;
Move the unsized array check to after the initializer has been
processed. If the array is still unsized, generate the error. This
should have no effect in GLSL ES 1.00 because, as previously mentioned,
array initializers are not allowed.

Newer graphic languages don't want messy float mask results but instead true
"boolean" mask results for float comparisons. Otherwise just need to convert
the floats back to integers. Need to keep the old opcodes however due to both
legacy (gl and d3d9) needing them and because older hw can't really deal with
integers. These new FSEQ/FSGE/FSLT/FSNE opcodes are part of integer API and
hence must be supported if a driver claims to support glsl 1.30 (or
PIPE_SHADER_CAP_INTEGERS).

Because we must maintain an exec_mask even if there's currently nothing
on the mask stack, we can still have an exec_mask at the end of the program.
Effectively, this mask should be set back to default when returning from main.
Without relying on END/RET opcode (I think it's valid to have neither) it is
actually difficult to do this, as there doesn't seem any reasonable place to
do it, so instead let's just say the exec_mask is invalid outside main (which
it really is effectively).
The problem is that geometry shader called end_primitive outside the shader
(in the epilogue), and as a result used a bogus mask, leading to bugs if we
had to set the (somewhat misnamed) ret_in_main bit anywhere. So just avoid
the mask combining function when called from outside the shader.

Instead of reducing masks to 0/1 simply use the mask directly as -1.
Also use some signed comparison instead of unsigned (as far as I understand

Many GLSL shaders contain code of the form:
x = condition ? foo : bar
The compiler emits an ir_if tree for this, since each subexpression
might be a complex tree that could have side-effects and short-circuit
logic operations.
However, the common case is to simply pick one of two constants or
variable's values---which is exactly what SEL is for. Replacing IF/ELSE
with SEL also simplifies the control flow graph, making optimization
passes which work on basic blocks more effective.

The instruction

Unlike most predicated instructions, it always writes to dst.
fs_inst::is_partial_write() is supposed to return true if the whole
register is guaranteed to be written. The !inst->predicated check makes
sense for most instructions, which might not write the whole register,
but SEL is a special case.
This caused live interval analysis to ignore the destination of
predicated SEL instructions when computing "def" information.

The existing inst->is_partial_write() already disallows predicated
instructions, so this has no functional change. However, it's worth
doing explicitly since the CSE pass does not consider the flag register.
This means it could blindly factor out operations that use the same
