[mips][microMIPS] Add microMIPS32r6 and microMIPS64r6 tests for existing 16-bit ADDIUR1SP, ADDIUR2, ADDIUS5 and ADDIUSP instructions

[zbuljan]

Summary

The patch adds microMIPS32r6 and microMIPS64r6 tests for existing 16-bit ADDIUR1SP, ADDIUR2, ADDIUS5 and ADDIUSP instructions.

[zbuljan]

Added disassembler tests for instructions.

LGTM, possibly with a couple nits.

test/MC/Mips/micromips32r6/invalid.s

6–7

Should these (and the one on line 4) be:

error: immediate operand value out of range

If so, they should be in invalid-wrong-error.s. If the current error is the one we want then it's ok here.

test/MC/Mips/micromips64r6/invalid.s

7–8

Likewise.
