  [NFC][AMDGPU] Add a test that can cause backend crash (#145777)

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.
