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
