b398b8ff1b Registers: Add a registers.hh file as an ISA switched header. 
This file is for register indices, Num* constants, and register types.
copyRegs and copyMiscRegs were moved to utility.hh and utility.cc.

32daf6fc3f Registers: Add an ISA object which replaces the MiscRegFile. 
This object encapsulates (or will eventually) the identity and characteristics
of the ISA in the CPU.

6e286cddfa Get rid of the immediate and displacement components of the EmulEnv struct and use them directly out of the instruction. The extra copies are conceptually realistic but are just innefficient as implemented. Also don't use the zeroeth microcode register for general storage since it's now the zero register, and implement a load and a store microops.

75e8838ba4 Clean up the code a little, fix (I think) a perceived problem with immediate sizes, and sign extend the 32-bit-acting-like-64-bit-immediates.

ce18d900a1 Replaced makeExtMI with predecode. 
Removed the getOpcode function from StaticInst which only made sense for Alpha.
Started implementing the x86 predecoder.

src/arch/x86/utility.hh:
    add hook for system to startup the cpu or not... in the case of FS sparc, only the first cpu would get spunup.. the rest sit in an idle state until they get an ipi
src/arch/sparc/isa/decoder.isa:
    handle writable bits of strandstatus register in miscregfile
src/arch/sparc/miscregfile.hh:
    some constants for the strand status register
src/arch/sparc/ua2005.cc:
    properly implement the strand status register
src/dev/sparc/iob.cc:
    implement ipi generation properly
src/sim/system.cc:
    call into the ISA to start the CPU (or not)
