Andrea Di Biagio f033db57e9 [TTI] Improved cost heuristic for cttz/ctlz calls. ... This patch is a follow-up of r228826 (see code-review: D7506). Now that SimplifyCFG uses TargetTransformInfo for cost analysis, we have to fix the cost heuristic for intrinsic calls to cttz/ctlz. This patch defines method 'getIntrinsicCost' in BasicTTIImpl: now, BasicTTIImpl queries TLI to check if a call to cttz/ctlz is cheap for the target. Added test cases in Transforms/SimplifyCFG/X86 to verify that on x86, SimplifyCFG only speculates a call to cttz/ctlz if it is cheap.
