Add a BlockInfo::FirstDef field. This is either an invalid SlotIndex, or valno->def for the first value defined inside the block. PHI values are not counted as defined inside the block. The FirstDef field will be used when estimating the cost of spilling around a block. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136736 91177308-0d34-0410-b5e6-96231b3b80d8
