Factor mangled id computation

[Diego Novillo, 2011-10-30 22:20:52]

This factors the computation of mangled names so it can be called
without actually setting the assembler name on the DECL.  It is used
in the pph branch for merging symbols that are replicated in multiple
images.

On trunk, it changes nothing, but it sets it up for when we are ready
to merge the pph branch.  OK for trunk?


Thanks.  Diego.


	* mangle.c (get_mangled_id): Factor from ...
	(mangle_decl): ... here.
	Call get_mangled_id.
