Add "Restored" flag to CalleeSavedInfo The liveness-tracking code assumes that the registers that were saved in the function's prolog are live outside of the function. Specifically, that registers that were saved are also live-on-exit from the function. This isn't always the case as illustrated by the LR register on ARM.
