Mikael Holmen 07f1e2e2b3 [RegAllocGreedy]: Allow recoloring of done register if it's non-tied 
Summary:
If we have a non-allocated register, we allow us to try recoloring of an
already allocated and "Done" register, even if they are of the same
register class, if the non-allocated register has at least one tied def
and the allocated one has none.

It should be easier to recolor the non-tied register than the tied one, so
it might be an improvement even if they use the same regclasses.
