re PR sanitizer/70683 (-fcompare-debug bug with -fsanitize=address)
PR sanitizer/70683
* tree-core.h (enum operand_equal_flag): Add OEP_NO_HASH_CHECK.
* fold-const.c (operand_equal_p): If flag_checking and
OEP_NO_HASH_CHECK is not set in flag, recurse with OEP_NO_HASH_CHECK
and if it returns non-zero, assert iterative_hash_expr on both
args is the same.
