Add VirtRegMap::rewrite() and use it in the new register allocators.
The rewriter works almost identically to -rewriter=trivial, except it also
eliminates any identity copies.
This makes the new register allocators independent of VirtRegRewriter.cpp which
will be going away at the same time as RegAllocLinearScan.
