Correct the definitions of ei, di, eret, deret, wait, syscall and break. Also provide microMIPS specific aliases to match the MIPS aliases. Additionally correct the definition of the wait instruction so that it is present in the instruction mapping tables. Reviewers: smaksimovic, abeserminji, atanasyan Differential Revision: https://reviews.llvm.org/D45939 llvm-svn: 330952
