arsenm added a child revision: D78020: clang/AMDGPU: Assume denormals are enabled for the default target..

I didn't realize HIP was a distinct offloading kind, so the subtarget
was looking for -march, which isn't correct for HIP. We also have the
possibility of different denormal defaults in the case of multiple
offload targets, so we need to thread the JobAction through the target
hook.
