bors 2ceed0b6cb Auto merge of #113814 - ChoKyuWon:master, r=davidtwco 
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.

README.md

The codegen crate contains the code to convert from MIR into LLVM IR, and then from LLVM IR into machine code. In general it contains code that runs towards the end of the compilation process.

For more information about how codegen works, see the rustc dev guide.
