i965/fs: Allow spilling for SIMD16 compute shaders
For fragment shaders, we can always use a SIMD8 program. Therefore, if
we detect spilling with a SIMD16 program, then it is better to skip
generating a SIMD16 program to only rely on a SIMD8 program.
Unfortunately, this doesn't work for compute shaders. For a compute
shader, we may be required to use SIMD16 if the local workgroup size
is bigger than a certain size. For example, on gen7, if the local
workgroup size is larger than 512, then a SIMD16 program is required.

glcpp: Implicitly resolve version after the first non-space/hash token.
We resolved the implicit version directive when processing control lines,
such as #ifdef, to ensure any built-in macros exist. However, we failed
to resolve it when handling ordinary text.
For example,
int x = __VERSION__;
should resolve __VERSION__ to 110, but since we never resolved the implicit
version, none of the built-in macros exist, so it was left as is.
This also meant we allowed the following shader to slop through:
123
#version 120
Nothing would cause the implicit version to take effect, so when we saw
the #version directive, we thought everything was peachy.
This patch makes the lexer's per-token action resolve the implicit
version on the first non-space/newline/hash token that isn't part of
a #version directive, fulfilling the GLSL language spec:
"The #version directive must occur in a shader before anything else,
except for comments and white space."
Because we emit #version as HASH_TOKEN then VERSION_TOKEN, we have to
allow HASH_TOKEN to slop through as well, so we don't resolve the
implicit version as soon as we see the # character. However, this is
fine, because the parser's HASH_TOKEN NEWLINE rule does resolve the
version, disallowing cases like:
#
#version 120
This patch also adds the above shaders as new glcpp tests.

i965/vec4: Propagate swizzles correctly during copy propagation.
This simplifies the code that iterates over the per-component values
found in the matching copy_entry struct and checks whether the
register regions that were copied to each component are similar enough
to be treated as a single (reswizzled) value which can be propagated
into the current instruction.
Aside from being scattered between opt_copy_propagation(),
try_copy_propagate(), and try_constant_propagate(), what I found
terribly confusing about the preexisting logic was that
opt_copy_propagation() tried to reorder the array of values according
to the swizzle of the instruction source, which meant one would have
had to invert the reordering applied at the top level in order to find
out which component to take from each value (we were just taking the
i-th component from the i-th value, which is not correct in general).
The saturate mask was also being swizzled incorrectly.
This consolidates the logic for matching multiple components of a
copy_entry into a single function which returns the result as a
regular src_reg on success, as if the copy had been performed with a
single MOV instruction copying all components of the src_reg into the
destination.

glsl: apply align layout qualifier rules to block offsets
From Section 4.4.5 (Uniform and Shader Storage Block Layout
Qualifiers) of the OpenGL 4.50 spec:
"The align qualifier makes the start of each block member have a
minimum byte alignment. It does not affect the internal layout
within each member, which will still follow the std140 or std430
rules. The specified alignment must be a power of 2, or a
compile-time error results.
The actual alignment of a member will be the greater of the
specified align alignment and the standard (e.g., std140) base
alignment for the member's type. The actual offset of a member is
computed as follows: If offset was declared, start with that
offset, otherwise start with the next available offset. If the
resulting offset is not a multiple of the actual alignment,
increase it to the first offset that is a multiple of the actual
alignment. This results in the actual offset the member will have.
When align is applied to an array, it affects only the start of
the array, not the array's internal stride. Both an offset and an
align qualifier can be specified on a declaration.
The align qualifier, when used on a block, has the same effect as
qualifying each member with the same align value as declared on
the block, and gets the same compile-time results and errors as if
this had been done. As described in general earlier, an individual
member can specify its own align, which overrides the block-level
align, but just for that member.

i965/vec4: add opportunistic behaviour to opt_vector_float()
opt_vector_float() transforms several scalar MOV operations to a single
vectorial MOV.
This is done when those MOV covers all the components of the destination
register. So something like:
mov vgrf3.0.xy:D, 0D
mov vgrf3.0.w:D,
1065353216D
mov vgrf3.0.z:D, 0D
is transformed in:
mov vgrf3.0:F, [0F, 0F, 0F, 1F]
But there are cases where not all the components are written. For
example, in:
mov vgrf2.0.x:D,
1073741824D
mov vgrf3.0.xy:D, 0D
mov vgrf3.0.w:D,
1065353216D
mov vgrf4.0.xy:D,
1065353216D
mov vgrf4.0.w:D, 0D
mov vgrf6.0:UD, u4.xyzw:UD
Nor vgrf3 nor vgrf4 .z components are written, so the optimization is
not applied.
But it could be applied anyway with the components covered, using a
writemask to select the ones written. So we could transform it in:
mov vgrf2.0.x:D,
1073741824D
mov vgrf3.0.xyw:F, [0F, 0F, 0F, 1F]
mov vgrf4.0.xyw:F, [1F, 1F, 0F, 0F]
mov vgrf6.0:UD, u4.xyzw:UD

i965/formatquery: Add support for INTERNALFORMAT_PREFERRED query
This pname is tricky. The spec states that an internal format should be
returned, that is compatible with the passed internal format, and has
at least the same precision. There is no clear API to resolve this.
The closest we have (and what other drivers (i.e, NVidia proprietary) do,
is to return the same internal format given as parameter. But we validate
first that the passed internal format is supported by i965.
To check for support, we have the TextureFormatSupported map'. But
this map expects a 'mesa_format', which takes a format+typen. So, we must
first "come up" with a generic type that is suited for this internal format,
then get a mesa_format, and then do the validation.
The cleanest solution here is to add a method that does exactly what
the spec wants: a driver's preferred internal format from a given
internal format. But at this point we lack a clear view of what
defines this preference, and also there seems to be no API for it.
