Fix a bug in the A57FPLoadBalancing register tracking/scavenger.
The code in AArch64A57FPLoadBalancing::scavengeRegister() to handle dead defs
was not correctly handling aliased registers. E.g. if the dead def was of D2,
then S2 was not being marked as unavailable, so it could potentially be used
across a live-range in which it would be clobbered.
Patch by Geoff Berry <gberry@codeaurora.org>!
