re PR tree-optimization/56448 (cc1 hangs on volatile array with -O or above)
PR tree-optimization/56448
* fold-const.c (operand_equal_p) <case tcc_reference>: Don't look at
TREE_SIDE_EFFECTS if flags contain OEP_CONSTANT_ADDRESS_OF.
Clear OEP_CONSTANT_ADDRESS_OF from flags before recursing on second or
later operands of the references, or even first operand for
INDIRECT_REF, TARGET_MEM_REF or MEM_REF.
* gcc.c-torture/compile/pr56448.c: New test.
