[LLVM][CodeGen][AArch64] Improve PTEST removal by looking through copies. (#132041)
The general predicates of the PTEST and PTEST_like instructions may
belong to different register classes. This can lead to the insertion of
a COPY instruction, making them appear different. However, for the
purpose of PTEST removal, such copies are irrelevant, and we can look
through them to improve the likelihood of finding a match.
