re PR c++/71372 (C++ FE drops TREE_THIS_VOLATILE in cp_fold on all tcc_reference trees)
PR c++/71372
* cp-gimplify.c (cp_fold): For INDIRECT_REF, if the folded expression
is INDIRECT_REF or MEM_REF, copy over TREE_READONLY, TREE_SIDE_EFFECTS
and TREE_THIS_VOLATILE flags. For ARRAY_REF and ARRAY_RANGE_REF, copy
over TREE_READONLY, TREE_SIDE_EFFECTS and TREE_THIS_VOLATILE flags
to the newly built tree.
* c-c++-common/pr71372.c: New test.
