Reviewers: Kevin Millikin, iposva, Message: This is now separated from the changes to VisitCompare. The register-to-register part of MergeTo, implemented simply. We can use xchg instruction on register cycles, if needed, after checking about its performance.
Description: Merge virtual frames by copying registers to registers. Also make Result destructor decrement register allocator usage count, and fix typo.
