tree-optimization/109491 - ICE in expressions_equal_p
At some point I elided the NULL pointer check in expressions_equal_p
because it shouldn't be necessary not realizing that for example
TARGET_MEM_REF has optional operands we cannot substitute with
something non-NULL with the same semantics. The following does the
simple thing and restore the check removed in r11-4982.

* tree-ssa-sccvn.cc (expressions_equal_p): Restore the
NULL operands test.
