this was noticed by the ODR verifier.  For variables we get unique_name wrong
because we first bring it local and then test if it is global.
This makes the ODR unification based on aassembler name to go wrong.

Bootstrapped/regtested x86_64-linux, will commit it shortly.

	* ipa.c (function_and_variable_visibility): First remember function was global
	and then make it local.
