Ben Clayton 1a1b5278d5 tint/transform: Inline HLSL uniform / storage buffers
Change the DecomposeMemoryAccess to behave more like the DirectVariableAccess transform, in that it'll inline the access of buffer variable into the load / store helper functions, instead of passing the array down.

This avoids large array copies observed with FXC, which can have *severe* performance costs.

dan sinclair 7092786f31 Fixup return of HLSL sign to match WGSL.
The HLSL `sign` method returns an `int` result (scalar or vector). The
WGSL `sign` expects the result to be the same type as the argument. This
CL injects a cast to the correct type after the `sign` call in the HLSL
generated source.

Ben Clayton be367b73ae Reduce shader complexity for external textures
Do more math on the CPU to avoid per-fragment ALU operations.
Use a mat3x2 instead of mat2x3 to avoid padding.

Ben Clayton 7d34de88f1 tint/test-runner: Split expectations for FXC and DXC
Change tint's `--fxc` flag to take the path of the FXC compiler DLL.
Have tint attempt to validate with both FXC and DXC if `--validate` is
passed.

Fix the 'dirsWithNoPassExpectations' logic which looks like it got
broken with the tint -> dawn merge. It also incorrectly applied
filepath.FromSlash() on windows.
