yes, i pushed down Simple into EmitCFIStartProc with the hope that someone
would actually know what to do with it. the spec says:

    Unless .cfi_startproc is used along with parameter simple it also emits
    some architecture dependent initial CFI instructions. 

now i have no idea what those arch dependent insns are or whether llvm already
emits them so any help is welcome ;).
