speculate calls to cttz/ctlz. SimplifyCFG now knows how to speculate calls to intrinsic cttz/ctlz that are 'cheap' for the target. Therefore, some of the logic in CodeGenPrepare that was originally added at revision 224899 can now be removed. This patch is basically a no functional change. It removes the duplicated logic in CodeGenPrepare and converts all the existing target specific tests for cttz/ctlz into SimplifyCFG tests.
