Non-comprehensive list of changes in this release
We've also improved the X86 and ARM cost model.
+ TargetTransformInfo
+ -------------------
+ TargetTransformInto (TTI) is a new interface that can be used by IR-level passes
+ to obtain target-specific information, such as the costs of instructions. Only "Lowering"
+ passes such as LSR and the vectorizer are allowed to use the TTI infrastructure.
