[mips][microMIPS] Implement SHRA[_R].PH, SHRAV[_R].PH, SHRAV[_R].QB, SHRAV_R.W, SHRA_R.W, SHRL.PH, SHRL.QB, SHRLV.PH and SHRLV.QB instructions

[zbuljan]

Summary

The patch implements microMIPSDSP instructions: SHRA[_R].PH, SHRAV[_R].PH, SHRAV[_R].QB, SHRAV_R.W, SHRA_R.W, SHRL.PH, SHRL.QB, SHRLV.PH and SHRLV.QB

[dsanders]

LGTM with some additional tests to cover out-of-range immediates (e.g. something like the tests for the 'align' instruction immediate in test/MC/Mips/mips32r6/invalid.s).
