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.

mov vgrf3.0.z:D, 0D

mov vgrf3.0.w:D,

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,

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.

The main reason is simplicity. The other option would be C&P how we
implemented the support of GL_MAX_{WIDTH/HEIGHT/DEPTH} and GL_SAMPLES.
Additionally, doing this way, we avoid adding checks on the code, as
are done by the call to the query itself.
MAX_COMBINED_DIMENSIONS is the only pname pointed on the spec of
needing a 64-bit query. We handle that possibility by packing the
returning value on the two first 32-bit integers of params. This
would work on the 32-bit query as far as the value is not greater
that INT_MAX. On the 64-bit query wrapper we unpack those values
in order to get the final value.

main/formatquery: support for MAX_{WIDTH/HEIGHT/DEPTH/LAYERS}
Implemented by calling GetIntegerv with the equivalent pname and
handling individually the exceptions related to dimensions.
All those pnames are used to get the maximum value for each dimension
of the given target. The only difference between this calls and
calling GetInteger with pnames like GL_MAX_TEXTURE_SIZE,
GL_MAX_3D_TEXTURE_SIZE, etc is that GetInternalformat allows to
specify a internalformat.
But at this moment, there is no reason to think that the values would
be different based on the internalformat. The spec already take that
into account, using these specific pnames as example on Issue 7 of
arb_internalformat_query2 spec.
So this seems like a hook to allow to return different values based on
the internalformat in the future.
It is worth to note that the piglit test associated to those pnames
are checking the returned values of GetInternalformat against the
values returned by GetInteger, and the test is passing with NVIDIA
proprietary drivers.

mesa/formatquery: support for IMAGE_FORMAT_COMPATIBILITY_TYPE
From arb_internalformat_query2 spec:
"IMAGE_FORMAT_COMPATIBILITY_TYPE: The matching criteria use for the
resource when used as an image textures is returned in
<params>. This is equivalent to calling GetTexParameter with <value>
set to IMAGE_FORMAT_COMPATIBILITY_TYPE."
Current implementation of GetTexParameter for this case returns a
field of a texture object, so the support of this pname was
implemented creating a temporal texture object and returning that
value.
It is worth to mention that right now that field is not reassigned
after initialization. So it is somehow hardcoded. An alternative
option would be return that value. That doesn't seems really scalable
though.

mesa/formatquery: handle unmodified buffer for SAMPLES on the 64-bit query
From arb_internalformat_query2 spec:
" If <internalformat> is not color-renderable, depth-renderable, or
stencil-renderable (as defined in section 4.4.4), or if <target>
does not support multiple samples (ie other than
TEXTURE_2D_MULTISAMPLE, TEXTURE_2D_MULTISAMPLE_ARRAY, or
RENDERBUFFER), <params> is not modified."
So there are cases where the buffer should not be modified. As the
64-bit query is a wrapper over the 32-bit query, we can't just copy
the values to the equivalent 32-bit buffer, as that would fail if the
original params contained values greater that INT_MAX. So we need to
copy-back only the values that got modified by the 32-bit query. We do
that by filling the temporal buffer by negatives, as the 32-bit query
should not return negative values ever.

"- INTERNALFORMAT_RED_SIZE
- INTERNALFORMAT_GREEN_SIZE
- INTERNALFORMAT_BLUE_SIZE
- INTERNALFORMAT_ALPHA_SIZE
- INTERNALFORMAT_DEPTH_SIZE
- INTERNALFORMAT_STENCIL_SIZE

actual resolutions that would be used for storing image array components
for the resource.
For compressed internal formats, the resolutions returned specify the
component resolution of an uncompressed internal format that produces
an image of roughly the same quality as the compressed algorithm.
For textures this query will return the same information as querying
GetTexLevelParameter{if}v for TEXTURE_*_SIZE would return.
If the internal format is unsupported, or if a particular component is
not present in the format, 0 is written to <params>.

For uncompressed internal formats, queries for these values return the
data type used to store the component.
For compressed internal formats the types returned specify how components
are interpreted after decompression.
For textures this query returns the same information as querying
GetTexLevelParameter{if}v for TEXTURE_*TYPE would return.
Possible values return include, NONE, SIGNED_NORMALIZED,
