* gimple-pretty-print.c (dump_ssaname_info): Print newline also
in case of VR_VARYING. Print get_nonzero_bits if not all ones.
* tree-ssanames.h (struct range_info_def): Add nonzero_bits field.
(set_nonzero_bits, get_nonzero_bits): New prototypes.
* tree-ssa-ccp.c (get_default_value): Use get_range_info to see if
a default def isn't partially constant.
(ccp_finalize): If after IPA, set_range_info if integral SSA_NAME
is known to be partially zero.
(evaluate_stmt): If we'd return otherwise VARYING, use get_range_info
to see if a default def isn't partially constant.
* tree-ssanames.c (set_range_info): Initialize nonzero_bits upon
creation of a range, if VR_RANGE, try to improve nonzero_bits from
the range.
(set_nonzero_bits, get_nonzero_bits): New functions.
* g++.dg/warn/pr33738.C (main): Initialize a2 again to make sure
we warn about it already during VRP1 pass.
