[pushed] c++: alias member template [PR100102]

Patrick already fixed the primary cause of this bug.  But while I was
looking at this testcase I noticed that with the qualified name k::o we
ended up with a plain FUNCTION_DECL, whereas without the k:: we got a
BASELINK.  There seems to be no good reason not to return the BASELINK
in this case as well.

Tested x86_64-pc-linux-gnu, applying to trunk.

	PR c++/100102

gcc/cp/ChangeLog:

	* init.c (build_offset_ref): Return the BASELINK for a static
	member function.

gcc/testsuite/ChangeLog:

	* g++.dg/cpp0x/alias-decl-73.C: New test.
