paul.lind d090469cdd Revert of MIPS: Add float instructions and test coverage, part one 
Reason for revert:
Simulator test failures in RunChangeFloat64ToInt.., RunChangeTaggedToInt32,
div-mul-minus-one

Original issue's description:

> Implement assembler, disassembler tests for all instructions for mips32
> and mips64. Additionally, add missing single precision float instructions
> for r2 and r6 architecture variants in assembler, simulator and disassembler
> with corresponding tests.
