13 years agoRevert to RA_Assign when a virtreg separates into components.

Revert to RA_Assign when a virtreg separates into components.

When dead code elimination deletes a PHI value, the virtual register may
split into multiple connected components. In that case, revert each
component to the RS_Assign stage.

The new components are guaranteed to be smaller (the original value
numbers are distributed among the components), so this will always be
making progress. The components are now allowed to evict other live
ranges or be split again.
