LOG: [Greedy RegAlloc] Fix the handling of split register in last chance re-coloring.
This is a fix for https://github.com/llvm/llvm-project/issues/55827.
When register we are trying to re-color is split the original register (we tried to recover)
has no uses after the split. However in rollback actions we assign back physical register to it.
Later it causes different assertions. One of them is in attached test.
This CL fixes this by avoiding assigning physical register back to register which has no usage
or its live interval now is empty.

; This testcase fails register allocation at the same time it performs
; virtual register splitting (by introducing VGPR to AGPR copies). We
; still need to enqueue and allocate the newly split vregs after the
; failure.
+; The machine verifier complains about usage of register
+; which is marked as killed in previous instruction.
+; This happens due to when register allocator is out of registers
+; it takes the first avialable register.
