* tree.c (get_unwidened): Decide whether to narrow a bitfield
reference based on TYPE_SIZE, not TYPE_PRECISION.
* cp/cvt.c (convert_to_void): Don't warn about the RHS of a comma
being useless if TREE_NO_UNUSED_WARNING is set.
* stmt.c (parse_output_constraint): Warn about in-out constraint
that doesn't allow a register.
(parse_input_constraint): Warn about matching constraint that
doesn't allow a register.
