Mark Lacey e742d68736 Auto-compute live intervals on demand. ... When new virtual registers are created during splitting/spilling, defer creation of the live interval until we need to use the live interval. Along with the recent commits to notify LiveRangeEdit when new virtual registers are created, this makes it possible for functions like TargetInstrInfo::loadRegFromStackSlot() and TargetInstrInfo::storeRegToStackSlot() to create multiple virtual registers as part of the process of generating loads/stores for different register classes, and then have the live intervals for those new registers computed when they are needed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@188437 91177308-0d34-0410-b5e6-96231b3b80d8		2013-08-14 23:50:16 +00:00
