[ARM][AArch64] Make ACLE __clzl/__clzll return unsigned int instead of unsigned long/uint64_t.
Use unsigned long in place of uint32_t for both clz and cls.
As far as I can tell this matches what ACLE defines and what gcc implements.
Noticed while investigating fixing https://github.com/llvm/llvm-project/issues/63113
