  [NFC][AMDGPU] Add a test that can cause backend crash

The crash was reported downstream, but it has been fixed in upstream by 2bada417c1f06361f4b7a992224bfb8e32d55ca6.
This PR is to add the test case upstream. Note that there are some UBs in the
IRs, such as load/store from/to a nullptr. The crash would not be reproducible
if any of them is changed to something else.
