Qizhi Hu 2fe5b15718 [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.
