Subject: c-common.c (c_alignof, [...]): Move here...

        * c-common.c (c_alignof, c_alignof_expr): Move here...
        * c-typeck.c: ...from here.
        * c-tree.h, c-common.h: Adjust.

        * tree.c (cp_build_qualified_type_real): Use get_qualified_type.
        (build_cplus_array_type): Use cp_build_qualified_type, not
        TYPE_MAIN_VARIANT, to get an unqualified version.

        * decl2.c (grok_alignof): Lose.
        (build_expr_from_tree): Use expr_sizeof and c_alignof_expr.
        * typeck.c (c_alignof): Lose.
        * semantics.c (finish_sizeof, finish_alignof): New.
        * parse.y: Use them.
        * cp-tree.h: Declare them.
