This adds the minimum necessary to support codegen for simple ALU operations on RV32. Prolog and epilog insertion, support for memory operations etc etc follow in future patches. Leave guessInstructionProperties=1 until https://reviews.llvm.org/D37065 is reviewed and lands. Differential Revision: https://reviews.llvm.org/D29933 llvm-svn: 316188
