[PATCH] D38128: Handle COPYs of physregs better (regalloc hints)

[Nemanja Ivanovic via Phabricator via llvm-commits]

Just looking at the number and placement of reg-reg moves for PowerPC seems fine. It doesn't seem like there are regressions but no huge reduction in the number of copies. However, since the diff is without context, it's hard to tell exactly what is going on in the test cases. I'll apply this patch to ToT and have a look at how things change before signing off on the PPC changes.
