Quentin Colombet	97c05b52b4	[MC] Emit an error if cfi_startproc is used before a symbol is defined.

[MC] Emit an error if cfi_startproc is used before a symbol is defined.

Currently, we bind those directives with the last symbol, so if none
has been defined, this would lead to a crash of the compiler.

Some autoconf tests use module level inline asm to test compiler's handling of

.cfi_startproc. e.g. libffi:

 $ cat confopt.c 
asm (".cfi_startproc\n\t.cfi_endproc");

int main () { return 0; }

Teach MC / dwarf emission to handle these cfi directives which essentially
create an empty frame.
