[PATCH] D91435: [AMDGPU] Split edge to make si_if dominate end_cf

[Alexander via Phabricator via llvm-commits]

New test created to cover both failed cases:

- end_cf in the block that has yet another predecessor besides that one defining the exec mask
- given the pattern above - not any visited node denotes a loop, only when we have a backage i.e. block's successor dominates the block.
