[PeepholeOptimizer] Refactor optimizeUncoalescable logic
Reapply r242294.
- Create a new CopyRewriter for Uncoalescable copy-like instructions
- Change the ValueTracker to return a ValueTrackerResult
This makes optimizeUncoalescable looks more like optimizeCoalescable and
use the CopyRewritter infrastructure.
This is also the preparation for looking up into PHI nodes in the
ValueTracker.
