    Running something like `clang-dxc.exe -T cs_6_2 x.hlsl` does one of two silly things, depending on whether `dxv` is on your path:
- warning: dxv not found; resulting DXIL will not be validated
- error: dxv command failed with exit code 1

The former makes sense when generating a binary (ie, with `-Fo out.dxil`), but it doesn't really make sense when we're generating text since the validator needs a binary anyway. The latter is even sillier, and results in all compiles to textual IR to fail if `dxv` is on your path.

We should only attempt to run `dxv` from the driver when emitting an object.
