Auxiliary Functions and Formats for FP in general
arch/mips/isa/decoder.isa:
ISA Parser doesnt accept operands of different types in one instruction so fix this for unorderedFP functions...
Add basic support for Paired Singled (PS) FP ops which happen to be part of the MIPS 32-ASE but turned out to
be included in the MIPS32ISA manual... The PS instructions allow SIMD in a pipeline...
arch/mips/isa/formats/fp.isa:
Add some more Formats for FP operation. I will add some auxiliary code through these formats
to alleviate code redundancy in the decoder.isa
arch/mips/isa/operands.isa:
Add operands for Paired Singles Ops
arch/mips/isa_traits.cc:
removed convert&round function and replace with fpConvert.
The whole "rounding mode" stuff is something that should be considered for full-system mode...
Also added skeletons for the unorderedFP,truncFP,and condition code funcs.
arch/mips/isa_traits.hh:

There still needs to be a work around to handle the paired singles operations ...
arch/mips/isa/decoder.isa:
More revamping of the floating point ops in decoder.isa. Change all of the
"convert and round" functions to fpConvert. Also, the utility functions
roundFP, truncFP, and unorderedFP are in place everywhere. Things
have been set up to appropriately use the FP condition codes in the decoder.isa
The fp.isa format file and the isa_traits.cc file now needed to be updated
to implement the appropriate "backend" operations/functionality...
arch/mips/isa_traits.hh:
Remove convert & round functions
Add roundFP, truncFP,unorderedFP, and the get/setFPconditionCode

Floating Point Mips Tests still need to be added, tested, and debugged.
arch/mips/isa/decoder.isa:
Fix mult and multu instructions. This semantic error causes the problem: <int64> = <int32> * <int32>. Although I was placing
the output into a 64-bit integer the multiply was just doing a 32-bit multiply so the solution is to just use
the 'sd' & 'ud' operands so that the ISA parser will use the int64_t and uint64_t types in calculation.
