Matthias Braun 51687912a4 ARM: Fix cases where CSI Restored bit is not cleared ...

LR is an untypical callee saved register in that it is restored into a
different register (PC) and thus does not live-out of the return block.
This case requires the `Restored` flag in CalleeSavedInfo to be cleared.

This fixes a number of cases where this wasn't handled correctly yet.
