a91ee5abc2 FP programs are back to running... Condition Codes can be read and set...
Special Regs (Hi,Lo,FCSR) are now added to the operands for use in decoder.isa.

Now it's back to just debugging execution of code for the release (those unaligned
memory access instruction pairs are still quite the pain i might add)

arch/mips/isa_traits.hh:
    declare functions for .cc file
arch/mips/isa_traits.cc:
    delete unnecessary overloaded functions

    implement condition code functions

    implement round function
arch/mips/isa/base.isa:
    remove R31 constant... define in the operands.isa file instead
arch/mips/isa/decoder.isa:
    wholesale changes once again to FP.

    Now the FP Condition Codes are implemented and the FP programs can
    run and complete to finish.

    Use isnan() instead of my unorderedFP() function

    Also, we now access special regs such as HI,LO,FCSR,etc. just like we do any other reg. operand
arch/mips/isa/operands.isa:
    add more operands for special control regs in int and FP regfiles
arch/mips/isa/formats/branch.isa:
    use R31 instead of r31
arch/mips/isa/formats/fp.isa:
    use MakeCCVector to set Condition Codes in FCSR
arch/mips/regfile/float_regfile.hh:
    treat control regs like any other reg. Just Index them after the regular architectural registers
arch/mips/regfile/int_regfile.hh:
    treat hi,lo as regular int. regs w/special indexing
arch/mips/regfile/regfile.hh:
    no longer need for special register accesses with their own function.

a4ed65d0fa Start working on more complex FP tests
Debug FP instructions to handle these FP insts

arch/mips/isa/bitfields.isa:
    add Bitfield for Floating Point Condition Codes
arch/mips/isa/decoder.isa:
    Follow instruction naming style with FP single insts
    Send the float value to the convert&round functions in single FP
    add ll inst support
    add 'token' sc support
arch/mips/isa_traits.cc:
    Add SINGLE->WORD, WORD->SINGLE, & WORD->DOUBLE conversions
arch/mips/regfile.hh:
    update header files
arch/mips/regfile/float_regfile.hh:
    Add more FP registers
