My patch to walk_args_for_param to fix QImode complex args, didn't deal with
HImode ones. Those also had the same problem, but I'd not triaged the
testsuite enough to see at that point.
This patch reverts the change to nvptx_ptx_type_from_mode, instead moving the
call to arg_promotion into the path for both split and unsplit args.
This fixes the following testcases (in addition to the ones the earlier patch
fixed):
gcc.dg/compat/scalar-by-value-4
gcc.dg/compat/scalar-return-4
gcc.dg/compat/struct-by-value-12
