The patch adds CodeGen support for microMIPS32r6 SEL.*, SELEQZ, SELNEZ, SELEQZ.* and SELNEZ.* instructions:

  - added DAG pattern definitions for proper selection of instructions
  - separated microMIPS32r6 instructions from equivalent MIPS32r6 instructions using NotInMicroMips predicate
  - added relation between microMIPS32r6 and equivalent MIPS32r6 instructions
  - fixed wrong instruction names
  - updated .ll files with tests for microMIPS32r6 select instructions
