James Price 960aa2ee75 msl: Add ArrayLengthFromUniform transform
Generate a uniform buffer that will receive the lengths of all storage
buffers, and use this to implement calls to arrayLength(). The
transform is provided with a set of mappings from storage buffer
binding points to the corresponding index into the array of buffer
lengths. The transform reports whether it generated the uniform
buffers or not.

Use this transform from the MSL sanitizer, using the binding number as
the index into the array. This matches the behavior of spirv-cross,
and so works with how Dawn already produces this uniform buffer.

Ben Clayton 165512c57e writer/hlsl: Emit UBO as an array of vector
Instead of a ConstantBuffer.

HLSL requires that each structure field in a UBO is 16 byte aligned.
WGSL has much looser constraints with its UBO field alignment rules.

Instead generate an array of uint4 vectors, and index into this, much
like we index into [RW]ByteAddressBuffers for SSBOs.

Extend the DecomposeStorageAccess transform to support uniforms too.
This has been renamed to DecomposeMemoryAccess.

Antonio Maiorano adbbd0ba66 Validate scalar constructor and implement conversion to vecN<bool> in spir-v backend
After implementing validation and fairly exhaustive tests, discovered
that conversion of scalar vector to bool vector did not work in the
spir-v backend. For module scope variables, we use and rely on the
FoldConstants transform to ensure no conversion needs to take place.
This is necessary because we cannot easily introduce temporary values
and refer to them when casting at module scope. Note that for the same
reason, module-level conversions are always constant foldable, so this
works. For function-level conversions, implemented support to emit a
comparison against a zero value, and store the result in the bool
vector.
