[AArch64InstrInfo] Ignore debug insts in areCFlagsAccessedBetweenInstrs [7/14]
Summary:
Fix an issue where the presence of debug info could disable a peephole
optimization due to areCFlagsAccessedBetweenInstrs returning the wrong
result.
In test/CodeGen/AArch64/arm64-csel.ll, the issue was found in the
function @foo5, in which the first compare could successfully be
optimized but not the second.
