Since ifunc_resolver is only valid on FUNCTION_DECL, check ifunc_resolver
only on FUNCTION_DECL.

Please test it on Darwin.

Since ifunc_resolver isn't set when an error is detected, we should
lookup ifunc attribute in this case.

	PR target/85900
	PR target/85345
	* varasm.c (assemble_alias): Lookup ifunc attribute on error.

Dominique verified that it fixed all Darwin issues.  I am checking it
