PHI g_9 reduced for COND_EXPR in block 7 to g_8.
statement un-sinked:
k_22 = k_11 | iftmp.5_13;
Removing basic block 8
;; basic block 8, loop depth 0
;; pred: 7
# iftmp.5_13 = PHI <2(7)>
;; succ: 9
Looks like match-and-simplify phiopt does not take into account PHInodes ...

Note this is a latent bug since it was introduced by r12-1309-gc4574d23cb0734 .
I don't know what changed that cause the IR to be different on the trunk but I
just know it is a latent bug.

This patch adds a check in match_simplify_replacement to make sure the
middlebb

This was just a thinko from before.
Ok? Bootstrapped and tested on x86_64-linux-gnu with no regressions?
