Real HLSL files pull float3/float4x4 etc from hlsl.h (included automatically
via -finclude-default-header). TestTU builds against an in-memory filesystem
though, so hlsl.h isn't reachable there, you can see "Dropped diagnostic:
'hlsl.h' file not found" in the test output even though the build still
succeeds.
The typedef/attribute is a way around that missing header. It's not testing
HLSL's real type sugar, just the ExtVectorElementExpr/MatrixElementExpr hover
paths, so I used Clang's underlying vector/matrix extension attributes directly
instead. Open to a better way to do this if you know one.
