poly_int: bit_field_size/offset
verify_expr ensured that the size and offset in gimple BIT_FIELD_REFs
satisfied tree_fits_uhwi_p. This patch extends that so that they can
be poly_uint64s, and adds helper routines for accessing them when the
verify_expr requirements apply.

gcc/
* tree.h (bit_field_size, bit_field_offset): New functions.
* hsa-gen.c (gen_hsa_addr): Use them.
* tree-ssa-forwprop.c (simplify_bitfield_ref): Likewise.
(simplify_vector_constructor): Likewise.
* tree-ssa-sccvn.c (copy_reference_ops_from_ref): Likewise.
* tree-cfg.c (verify_expr): Require the sizes and offsets of a
BIT_FIELD_REF to be poly_uint64s rather than uhwis.
* fold-const.c (fold_ternary_loc): Protect tree_to_uhwi with
tree_fits_uhwi_p.
