re PR tree-optimization/48694 (possible memory hog bug)

PR middle-end/48694
* tree.h (OEP_CONSTANT_ADDRESS_OF): New operand_equal_flag.
* fold-const.c (operand_equal_p): For TREE_CONSTANT ADDR_EXPRs
compare the operands with OEP_CONSTANT_ADDRESS_OF.  Treat
trees with TREE_SIDE_EFFECTS equal when OEP_CONSTANT_ADDRESS_OF
is set.

* gcc.dg/torture/pr48694-1.c: New testcase.
* gcc.dg/torture/pr48694-2.c: Likewise.
