This small patch replaces pushdecl_with_scope with a more-specific 
pushdecl_outermost_localscope.  It's used in 2 places to inject an 
artifical decl into the outermost block scope of a function 
(__FUNCTION__ var and lambda capture proxies).

This moves some binding-level handling into name-lookup, where it belongs.

Applied to trunk.
