-The major change is for CMoveP and StrComp.  They have related but slightly
-different problems.  They both take in TWO oops which are both null-checked
-independently before the using Node.  After CCP removes the CastPP's they need
-to pick up the guarding test edge - in this case TWO control edges.  I tried
-various solutions, all have problems:
 
-(1) Do nothing.  This leads to a bug where we hoist a Load from a CMoveP or a
-StrComp above a guarding null check.  I've seen both cases in normal -Xcomp
-testing.
-
-(2) Plug the control edge from 1 of the 2 oops in.  Apparent problem here is
-to figure out which test post-dominates.  The real problem is that it doesn't
-matter which one you pick.  After you pick up, the dominating-test elider in
-IGVN can remove the test and allow you to hoist up to the dominating test on
-the chosen oop bypassing the test on the not-chosen oop.  Seen in testing.
-Oops.
-
-(3) Leave the CastPP's in.  This makes the graph more accurate in some sense;
-we get to keep around the knowledge that an oop is not-null after some test.
-Alas, the CastPP's interfere with GVN (some values are the regular oop, some
-are the CastPP of the oop, all merge at Phi's which cannot collapse, etc).
-This cost us 10% on SpecJVM, even when I removed some of the more trivial
-cases in the optimizer.  Removing more useless Phi's started allowing Loads to
-illegally float above null checks.  I gave up on this approach.
-
-(4) Add BOTH control edges to both tests.  Alas, too much code knows that
-control edges are in slot-zero ONLY.  Many quick asserts fail; no way to do
-this one.  Note that I really want to allow the CMoveP to float and add both
-control edges to the dependent Load op - meaning I can select early but I
-cannot Load until I pass both tests.
-
-(5) Do not hoist CMoveP and StrComp.  To this end I added the v-call
-depends_only_on_test().  No obvious performance loss on Spec, but we are
-clearly conservative on CMoveP (also so on StrComp but that's unlikely to
-matter ever).
