d3dcompiler and d3dx9 versions before 42 don't emit this error; this will be
necessary to emulate that behaviour.
Other warnings exist that are introduced in different d3dcompiler versions,
although there are not very many distinct HLSL warnings to begin with.
We could of course group all these together under a single compiler option, but
I find that using separate top-level options is unilaterally friendlier to an
API consumer, and simpler to implement as well. It also in some sense maps
conceptually to e.g. "-Wno-implicit-conversion".
Properly passing the inverse-trig.shader_test tests whose qualifiers
have been removed requires making spirv.c capable of handling ABS.
The same happens for the ps_3_0 equality test in
float-comparison.shader_test.

These may happen when storing to structured buffers, and we are not
handling them properly yet. The included test reaches unreacheable code
before this patch.
Storing to buffers is complicated since we need to split the index
chain in two paths:
- The path within the variable where the resource is.
- The subpath to the part of the resource element that is being stored
to.
For now, we will emit a fixme when the index chain in the lhs is not a
direct resource access.
