HOST_BITS_PER_WIDE_INT.
(verify_reg_in_set): New function, broken out of verify_reg_tracked.
(verify_reg_tracked): Use it.
(scan_rtx_reg): When seeing a use involving a superset of the
registers in an existing chain, enlarge that chain. Otherwise,
allow subsets and set fail_current_block for all other kinds of

(hide_operands): New argument UNTRACKED_OPERANDS; callers changed.
Do not modify operands when the bit with the corresponding number
is set in that bitmap.
(build_def_use): When we see matching operands with different
modes, don't set fail_current_block, but keep track of such
operands in a bitmap if their registers aren't already tracked
in an open chain. Pass this bitmap to all hide_operands calls.
