* Fixed label optimizer to work with MIPS, and enabled level 1 optimization for MIPS targets.
The difference in branch instruction formats is isolated in function JumpTargetOp, it is a plain function rather than a virtual method, so it can be easily inlined and, after inlining, produces the same code for non-MIPS targets as it was before change.
