Rework of the new interface for shrink wrapping Based on comments from Hal (http://lists.llvm.org/pipermail/llvm-commits/Week-of-Mon-20150810/292978.html), I've changed the interface to add a callback mechanism to the TargetFrameLowering class to query whether the specific target supports shrink wrapping. By default, shrink wrapping is disabled by default. Each target can override the default behaviour using the TargetFrameLowering::targetSupportsShrinkWrapping() method. Shrink wrapping can still be explicitly enabled or disabled from the command line, using the existing -enable-shrink-wrap=<true|false> option.
