Teach computeRegisterProperties() to compute "representative" register class for legal value types. A "representative" register class is the largest legal super-reg register class for a value type. e.g. On i386, GR32 is the rep register class for i8 / i16 / i32; on x86_64 it would be GR64. This property will be used by the register pressure tracking instruction scheduler. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@108735 91177308-0d34-0410-b5e6-96231b3b80d8
