Subject: Rename isLoopExit to isLoopExiting, for consistency with the wording
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=32663b719b4996b3a735f22bba80d771d50f96e7;p=oota-llvm.git

Rename isLoopExit to isLoopExiting, for consistency with the wording
used elsewhere - an exit block is a block outside the loop branched to
from within the loop. An exiting block is a block inside the loop that
branches out.
