[PATCH 08/14] cp/tree.c: strip location wrappers in lvalue_kind

[David Malcolm]

Without this, then lvalue_p returns false for decls, and hence
e.g. uses of them for references fail.

Stripping location wrappers in lvalue_kind restores the correct
behavior of lvalue_p etc.

gcc/cp/ChangeLog:
        * tree.c (lvalue_kind): Strip any location wrapper.
