Right, in which case we'll want to re-structure this code so that it can
handle a string of GIMPLE.  Perhaps we want to do it at the level of
fold_stmt.  Teach it to deal with situations that might require it to
emit more than one GIMPLE instruction.

For now, I'm OK with rejecting MODIFY_EXPRs only if their RHS is not a
gimple_val.
