Log Message
Remove outdated code:
The removed version with the loop registers saved on the stack was
originally intended to workaround the missing toolchain support for
LoopReg Clobbers.
Since our toolchain now supports these there is no point in keeping this
workaround. And since we don?\226?\128?\153t touch LoopRegs anymore we?\226?\128?\153re no longer
subject for ANOMALY_05000312.
