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.
