[PATCH] D40957: [X86] Fix crash caused by not properly marking visited registers in Domain Reassignment pass

[Guy Blank via Phabricator via llvm-commits]

guyblank created this revision.

The registers added to closures were not marked as such, causing registers to be in multiple closures. 
In some cases (like the added test) this caused an assertion to fail.
