Adds support for spilling previously allocated live intervals to handle cases in which a register is unavailable for spill code. Adds LiveIntervalUnion::extract. While processing interferences on a live virtual register, reuses the same Query object for each physcial reg. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118423 91177308-0d34-0410-b5e6-96231b3b80d8
