builtins.c (get_pointer_alignment): Honor DECL_ALIGN on a FUNCTION_DECL.

* builtins.c (get_pointer_alignment): Honor DECL_ALIGN on a FUNCTION_DECL. * tree.c (build_decl_stat): Move code from here... (make_node_stat): ... to here. Don't uselessly clear DECL_USER_ALIGN. (expr_align): Honor DECL_ALIGN on a FUNCTION_DECL. Add comment about using DECL_ALIGN of LABEL_DECL and CONST_DECL. * tree.h (DECL_USER_ALIGN): Fix misplaced comment. * varasm.c (assemble_start_function): Use DECL_ALIGN instead of FUNCTION_BOUNDARY.
