LiveRegUnits: Add accumulateBackward() function
This function can be used to accumulate the set of all read and modified
register in a sequence of instructions.
Use this code in AArch64A57FPLoadBalancing::scavengeRegister() to prove
the concept.
- The AArch64A57LoadBalancing code is using a backwards analysis now
which is irrespective of kill flags. This is the main motivation for
this change.
