crosstest/test_bitmanip_intrin.ll

; Wrappers around the bit manipulation intrinsics, which use name mangling
; for encoding the type in the name instead of plain "C" suffixes.
; E.g., my_ctpop(unsigned long long) vs __builtin_popcountll(...)
; Also, normalize the intrinsic to take a single parameter when there
; can be two, as is the case for ctlz and cttz.
