[NVPTX] Fixup NVPTXPrologEpilogPass for opt-bisect-limit (#144136)
Currently, the NVPTXPrologEpilogPass will crash if LIFETIME_START or
LIFETIME_END instructions are encountered. Usually this isn't a problem
since a couple earlier passes will always remove them. However, when
using opt-bisect-limit crashes can occur. This can hinder debugging and
reveals a potential future problem if these optimization passes change
their behavior. https://cuda.godbolt.org/z/E81xxKGdb
This change updates NVPTXPrologEpilogPass and
NVPTXRegisterInfo::eliminateFrameIndex to gracefully handle these
instructions by simply removing them. While I'm here I also did some
general fixup in NVPTXPrologEpilogPass to make it look more like
PrologEpilogInserter (from which it was copied).
