In HLSL itself it's allowed via the compat overloads, but this is just testing
the raw `__builtin_elementwise_pow`, which only accepts 16/32-bit float. So the
error is really about double rather than matrices.
There is actually a `half-float-only-errors2.hlsl` that already tests the
`atan2`, `pow`, and `fmod` builtins for `double` scalar and vector errors
though. I think it might make sense to put this matrix case there and drop
`pow_mat-errors.hlsl` and `atan2-errors_mat.hlsl` entirely. (fmod has no matrix
implementation yet, but I don't think that affects testing the builtin)
