mesa: Make GenerateMipmap check the target before finding an object.
If glGenerateMipmap was called with a bogus target, then it would
pass that to _mesa_get_current_tex_object(), which would raise a
_mesa_problem() telling people to file bugs. We'd then do the
proper error checking, raise an error, and bail.
Doing the check first avoids the _mesa_problem(). The DSA variant
doesn't take a target parameter, so we leave the target validation
exactly as it was in that case.
Fixes one dEQP GLES2 test:
dEQP-GLES2.functional.negative_api.texture.generatemipmap.invalid_target.

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.

i965: Add support for swizzling arbitrary immediates to (brw_)swizzle().
Scalar immediates used to be handled correctly by swizzle() (as the

never handled correctly, but we had ad-hoc code to swizzle VF
immediates in the vec4 copy propagation pass. This takes care of

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
This commit does precisely that: opportunistically apply
opt_vector_float() when possible.
