| for extreme large case. We had a case that a single loop which has 4000 exits and the average number of predecessors of each exit is > 1000, and we found compiling the case spent a significant amount of time on checking whether a loop has dedicated exits. This patch adds a limit for the iterations to the check. With the patch, the time to compile our testcase reduced from 1000s to 200s (clang release build).
