Move bitmask routines to vrange base class.
Any range can theoretically have a bitmask of set bits. This patch
moves the bitmask accessors to the base class. This cleans up some
users in IPA*, and will provide a cleaner interface when prange is in
place.
gcc/ChangeLog:
* ipa-cp.cc (propagate_bits_across_jump_function): Access bitmask
through base class.
(ipcp_store_vr_results): Same.
* ipa-prop.cc (ipa_compute_jump_functions_for_edge): Same.
(ipcp_get_parm_bits): Same.
(ipcp_update_vr): Same.
* range-op-mixed.h (update_known_bitmask): Change argument to vrange.
* range-op.cc (update_known_bitmask): Same.
* value-range.cc (vrange::update_bitmask): New.
(irange::set_nonzero_bits): Move to vrange class.
(irange::get_nonzero_bits): Same.
* value-range.h (class vrange): Add update_bitmask, get_bitmask,
get_nonzero_bits, and set_nonzero_bits.
(class irange): Make bitmask methods virtual overrides.
(class Value_Range): Add get_bitmask and update_bitmask.
