These are identical but use microMIPS instructions instead of MIPS instructions. Also, flatten the 'let AdditionalPredicates = [InMicroMips]' by using the ISA_MICROMIPS adjective. Add tests for constant materialization. Reviewers: atanasyan, abeserminji, smaksimovic Differential Revision: https://reviews.llvm.org/D48275 llvm-svn: 335185
