PR c++/70933
* tree-core.h (enum operand_equal_flag): Add OEP_HASH_CHECK.
* tree.c (inchash::add_expr): If !IS_EXPR_CODE_CLASS (tclass),
assert flags & OEP_HASH_CHECK, instead of asserting it
never happens. Handle TARGET_EXPR.
* fold-const.c (operand_equal_p): For hash verification,
or in OEP_HASH_CHECK into flags.
* g++.dg/opt/pr70906.C: New test.
* g++.dg/opt/pr70933.C: New test.
