[mips] Correct microMIP's jump and add unconditional branch pseudo Correct the definition of 'j' as being unavailable for microMIPS32R6 and provide the 'b' assembly idiom for codegen purposes for microMIPS32r3. Provide the necessary 'br' pattern for microMIPS32R6 as it now longer incorrectly uses the 'j' instruction.

Reland r331175: "[mips] Fix the predicates of jump and branch and link instructions" The previous version of this patch restricted the 'jal' instruction to MIPS and microMIPSr3. microMIPS32r6 does not have this instruction and instead uses jal as an alias for balc.
