Toma Tabacu e1e460dbc5 Recommit "[mips] [IAS] Add support for BNE and BEQ with an immediate operand." (r239396). 
Apparently, Arcanist didn't include some of my local changes in my previous
commit attempt.

Toma Tabacu 5fa8fb5762 [mips] [IAS] Add support for BNE and BEQ with an immediate operand. 
Summary:
For some branches, GAS accepts an immediate instead of the 2nd register operand.
We only implement this for BNE and BEQ for now. Other branch instructions can be added later, if needed.
