Dylan McKay c328fe5af4 [RegAllocGreedy] Attempt to split unspillable live intervals ... Summary: Previously, when allocating unspillable live ranges, we would never attempt to split. We would always bail out and try last ditch graph recoloring. This patch changes this by attempting to split all live intervals before performing recoloring. This fixes LLVM bug PR14879. I can't add test cases for any backends other than AVR because none of them have small enough register classes to trigger the bug.
