The only issue with the patch from Daniel Jacobowitz was a problem with
TARGET_EXPR, and I wasn't sure how to fix that. Meanwhile, Ulrich Weigand
checked in a patch May 1 to fix an aliasing problem with TARGET_EXPRs that was
apparently related to the problem I identified last year, as his patch is a
superset of mine. Therefore, it may be the case that Daniel's patch is OK now.
It needs retesting.
The SAVE_EXPR/var_temp_slot_level stuff is still broken. Someone needs to look
into that.
