lower_integer_multiplication() implements 32x32-bit multiplication on
some platforms by bit-casting one of the 32-bit sources into two
16-bit unsigned integer portions. This can give incorrect results if
the original instruction specified a source modifier. Fix it by
emitting an additional MOV instruction implementing the source
modifiers where necessary.

the naming is a bit confusing no matter how you look at it. Within SPIR-V
"global" memory is memory accessible from all threads. glsl "global" memory
normally refers to shader thread private memory declared at global scope. As
we already use "shared" for memory shared across all thrads of a work group
the solution where everybody could be happy with is to rename "global" to
"private" and use "global" later for memory usually stored within system
accessible memory (be it VRAM or system RAM if keeping SVM in mind).
glsl "local" memory is memory only accessible within a function, while SPIR-V
"local" memory is memory accessible within the same workgroup.

In the following scenario :
1. Create image format R8G8B8A8_UNORM
2. Create image view format R8G8B8A8_SRGB
3. Clear the view through a sub pass to a particular color
4. Barrier on the image to from color attachment to source transfer
5. Copy the image into a linear buffer to check the content
The step 4 resolving the clear color is unaware of the SRGB format of
the view, because the blorp resolve operations operate on images the
color associated with the resolve will not operate on SRGB format but
UNORM. Leading to the wrong color being written into surfaces.
This change forces a clear color resolve at the end of the render pass
so following resolves won't have to deal with the clear color with a
format that doesn't match the image's format.
On gfxbench vulkan_5_normal 1280x720, this appear to cost us ~0.5fps,
from 49.316 down to 48.949.

SPIR-V allows for matrix and array types to be decorated with explicit
byte stride decorations and matrix types to be decorated row- or
column-major. This commit adds support to glsl_type to encode this
information. Because this doesn't work nicely with std430 and std140
alignments, we add asserts to ensure that we don't use any of the std430
or std140 layout functions with explicitly laid out types.
In SPIR-V, the layout information for matrices is applied to the parent
struct member instead of to the matrix type itself. However, this is
gets rather clumsy when you're walking derefs trying to compute offsets
because, the moment you hit a matrix, you have to crawl back the deref
chain and find the struct. Instead, we take the same path here as we've
taken in spirv_to_nir and put the decorations on the matrix type itself.
This also subtly adds support for strided vector types. These don't
come up in SPIR-V directly but you can get one as the result of taking a
column from a row-major matrix or a row from a column-major matrix.

The loop through instructions doesn't set the cursor for us so unless we
set it somewhere, we may end up emitting instructions in the wrong
place. The only reason why we haven't been bitten by this in the past
is that it only happens in a few variable pointers cases and the CTS
tests for those don't use much control flow so things were getting
emitted in the correct order by accident.

We've made the choice not to use fast clears on layer > 0 with
multilayer images. This is partly because we would need to store
multiple clear colors for each layer, making the existing memory
layout, already including aux surfaces, fast clear color, image state,
etc... even more complex.
Partial resolves are the operations transfering the clear colors into
the auxiliary buffers. This operation is currently implemented in
Blorp by loading the clear color from the image's BO, into a shader
that then samples from the auxiliary buffer and writes the color only
if it isn't there already.
The problem here is that because we store only one clear color for all
layers and it is used for partial resolves. If you trigger a partial
clear on a layer > 0, then you're likely to deal with a color that is
not what you actually want. In the particular issues below, we have
multiple layers, each cleared with a different color but the partial
resolve just writes the wrong color into the auxiliary buffers for
layers > 0.
