Added TargetRegisterInfo::getAllocatableClass. The ensures that virtual registers always belong to an allocatable class. If your target attempts to create a vreg for an operand that has no allocatable register subclass, you will crash quickly. This ensures that targets define register classes as intended. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@156046 91177308-0d34-0410-b5e6-96231b3b80d8
