In preparation for using the new register scavenger capability for providing more than one register simultaneously, specifically note functions that have spilled VRSAVE (currently, this can happen only in functions that use the setjmp intrinsic). As with CR spilling, such functions will need to provide two emergency spill slots to the scavenger. No functionality change intended. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@177832 91177308-0d34-0410-b5e6-96231b3b80d8
