c,c++: Fix incorrect warning with asm defined symbols

Static symbols defined in assembly cause wrong "used but never defined"
warning.

static void asm_fn();
asm("%cc0:" :: ":"(&asm_fn));

This happens in C,C++ frontends before cgraph is created where the
relevant flags are located.

We can suppress these warnings with OPT_Wunused.
C,C++ frontends and cgraphunit suppressed OPT_Wunused and
OPT_Wunused_function interchangeably, so we unify suppression to
only OPT_Wunused.

I would suggest to set TREE_ASM_WRITTEN if a static function is defined by a
toplevel asm and check that in the diagnostic.
