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
--HG--
rename : arch/mips/int_regfile.hh => arch/mips/regfile/int_regfile.hh
