  HIP: Try to deal with more llvm package layouts

The various HIP builds are all inconsistent.

The default llvm install goes to ${INSTALL_PREFIX}/bin/clang, but the
rocm packaging scripts move this under
${INSTALL_PREFIX}/llvm/bin/clang. Some other builds further pollute
this with ${INSTALL_PREFIX}/bin/x86_64/clang. These should really be
consolidated, but try to handle them for now.

  AMDGPU: Refine rcp/rsq intrinsic folding for modern FP rules

We have to assume undef could be an snan, which would need quieting so
returning qnan is safer than undef. Also consider strictfp, and don't
care if the result rounded.
