Anna Thomas 61540ac18b [RS4GC] Refactor code for Rematerializing in presence of phi. NFC ...

Summary:
This is an NFC refactoring change as a precursor to the actual fix for rematerializing in
presence of phi.
https://reviews.llvm.org/D24399

Pasted from review:
findRematerializableChainToBasePointer changed to return the root of the
chain. instead of true or false.
move the PHI matching logic into the caller by inspecting the root return value.
This includes an assertion that the alternate root is in the liveset for the
call.

Tested with current RS4GC tests.
