  Log Message:
  -----------
  AMDGPU: Stop adding stack passed wide arguments to call conv handler

The generated calling convention code shouldn't see these types since
we split large types into 32-bit chunks before the calling convention
code is triggered.

GlobalISel ends up directly calls the generated CC code before
checking for the register count breakdown. Arguably this difference is
a bug, but this was dead code for the DAG anyway.

  Log Message:
  -----------
  GlobalISel: Use correct calling convention in handleAssignments

This was using the calling convention of the calling function, not the
callee. Avoids regressions in a future patch.
