It shouldn't be.  In valid, renamed, up-to-date stmt's,
FOR_EACH_SSA_*_OPERAND can *only* return SSA_NAMEs.  Non-ssa names can
only occur when the stmt is not up to date, or before ssa renaming has
taken place.  

The operand cache exists only to access SSA_NAMEs easily. You should
never get anything else in an up-to-date stmt.
