* tree.def (BIT_FIELD_REF): Constrain result type and its precision.
* tree-cfg.c (verify_expr): Verify BIT_FIELD_REF constraints on
result type and precision.
* expr.c (get_inner_reference): Set unsignedp based on the result
type of BIT_FIELD_REF.
* tree.h (BIT_FIELD_REF_UNSIGNED): Remove.
* tree-sra.c (instantiate_element): Do not set BIT_FIELD_REF_UNSIGNED.
(try_instantiate_multiple_fields): Likewise. Use the correct type
for BIT_FIELD_REF.
(sra_build_assignment): Likewise.
(sra_build_elt_assignment): Likewise.
(sra_explode_bitfield_assignment): Likewise.
* print-tree.c (print_node): Do not check BIT_FIELD_REF_UNSIGNED.
* tree-vect-transform.c (vect_create_epilog_for_reduction): Do not
set BIT_FIELD_REF_UNSIGNED.
(vectorizable_load): Likewise.
