[PATCH] D38309: [RegAllocGreedy]: Allow recoloring of done register if it's non-tied

[Mikael Holmén via Phabricator via llvm-commits]

I found this problem on my out-of-tree target and the only reproducer I
have for it there is quite big and ugly so I've failed to make a nice
testcase out of it for an in-tree target.

I've run the benchmarks with

lnt runtest nt

on my x86 linux machine and computed checksums on the object files
and there is no difference with/without the patch.
