[PATCH 1/2] symtab: also change RTL decl name

[Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>]

We were changing the ASSEMBLER_NAME of the function decl
but not the name in DECL_RTL which is used as the function name
fnname in rest_of_handle_final(). This led to using the old, wrong name
for the attribute target default function when using target_clones.

Bootstrapped and regtested cleanly on x86_64-unknown-linux
for c,c++,fortran,lto.
Ok for trunk?

gcc/ChangeLog:

	* symtab.cc: Remove stray comment.
	(symbol_table::change_decl_assembler_name): Also update the
	name in DECL_RTL.
