[RFA:] PR37170, extern weak broken, like for gcc.dg/weak/weak-1.c

>> I might be able to help remove some FE calls to assemble_external.

I started with the C++ FE. The results are interesting. Just removing
all the 3 remaining calls produced no regressions  on X86_64 or i686
linux. I am trying to get a PPC64 machine to do a bit more testing,
but decided to post the patch earlier.

The bad news is that this was not one of the C++ problems in LTO.

	* class.c (build_vtbl_ref_1): Don't call assemble_external.
	* decl2.c (mark_used): Don't call assemble_external.
	* init.c (build_vtbl_address): Don't call assemble_external.
