[PR68083] don't introduce undefined behavior in ifcombine

The ifcombine pass may move a conditional access to an uninitialized
value before the condition that ensures it is always well-defined,
thus introducing undefined behavior. Stop it from doing so.

 * tree-ssa-ifcombine.c: Include tree-ssa.h.
 (bb_no_side_effects_p): Test for undefined uses too.
