  AMDGPU/GlobalISel: Fix skipping unused kernel arguments

The tests in a5b9ad7e9aca1329ba310e638dafa58c47468a58 actually failed
the verifier, which for some reason is not the default. Also add tests
for 0-sized function arguments, which do not add entries to the
expected register lists.

  Log Message:
  -----------
  GlobalISel: Handle EVT argument lowering correctly

handleAssignments was assuming every argument type is an MVT, and
assignArg would always fail. This fixes one of the hacks in the
current AMDGPU calling convention code that pre-processes the
arguments.
