On RISC-V, AArch64, and LoongArch, the `_mcount` function takes `__builtin_return_address(0)` as an argument since `__builtin_return_address(1)` is not available on these platforms. This patch fixes the argument passing to match the behavior of glibc/gcc. Closes https://github.com/llvm/llvm-project/issues/121103.
