c++: Set more DECL_CONTEXTs

Browse Source 
I discovered we were not setting DECL_CONTEXT in a few cases, and
grokfndecl's control flow wasn't making it clear that we were doing it
in all cases.

	gcc/cp/
	* cp-gimplify.c (cp_genericize_r): Set IMPORTED_DECL's context.
	* cp-objcp-common.c (cp_pushdecl): Set decl's context.
	* decl.c (grokfndecl): Make DECL_CONTEXT setting clearer.
