Replace the \01__gnu_mcount_nc to LLVM intrinsic for ARM
Current `-Zinstrument-mcount` for ARM32 use the `\01__gnu_mcount_nc` directly for its instrumentation function. However, the LLVM does not use this mcount function directly, but it wraps it to intrinsic, `llvm.arm.gnu.eabi.mcount` and the transform pass also only handle the intrinsic. As a result, current `-Zinstrument-mcount` not work on ARM32. Refer: https://github.com/namhyung/uftrace/issues/1764 This commit replaces the mcount name from native function to the LLVM intrinsic so that the transform pass can handle it.
