  -----------
  [Clang][Sema] improve sema check of clang::musttail attribute (#77727)

Call function with no-return attribute generates code with unreachable
instruction instead of return and if the call statement has
`clang::musttail` attribute, it would crash in `VerifyPass`. Check this
condition in Sema ahead.
Fix [issue](https://github.com/llvm/llvm-project/issues/76631)
