David Stuttard 82618baa0f [AMDGPU] Fix for issue in alloca to vector promotion pass ...

Summary:
Alloca promotion pass not dealing with non-canonical input

Added some additional checks so the pass simply backs-off forms it can't deal with (non-canonical)

Also added some test cases in non-canonical form to check that it no longer crashes
