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.

David Neto 1e19b55d19 spirv-reader: switch to HLSL-style pipeline IO
- When storing to sample_mask output, write to the 0th element
- Only make a return struct if it has members
- Adjust type signedness coercion when loading special builtins.
- Adapt tests

- Update expectations for end-to-end tests

- Handle sample_mask with stride
  Input variables normally don't have layout. But they can have it
  up through SPIR-V 1.4.
  Handle this case in the SPIR-V reader, by seeing through the
  intermediate alias type created for the strided array type.

Ben Clayton 5d2f34ecf2 writer/hlsl: Simplify emission logic, clean up output
And fix issues where global variables would not be emitted unless they were transitively referenced by an entry point.

This change requires crbug.com/tint/697 to be fixed before landing.

Ben Clayton ada560b289 writer/hlsl: Fix continuing block emission
Inline the `continuing` block in the places where `continue` is called.

Simplifies the emission, and fixes emission of `let` statements in the loop.

Also fix random indenting of intrinsic functions.
