The shadow registers are folded into the normal integer registers to ease renaming indexing.
Include the removed Opcdec class of instructions for faulting when a pal mode only instruction is decoded in non-pal mode.

Changes to automatically map the shadow registers if the instruction is in PAL mode.

arch/alpha/isa/unimp.isa:
Changes for automatically using the shadow registers. Now instructions must decode based on an ExtMachInst, which is a MachInst with any decode context information concatenated onto the higher order bits.
arch/alpha/isa/main.isa:
Changes for automatically using the shadow registers. Now instructions must decode based on an ExtMachInst, which is a MachInst with any decode context information concatenated onto the higher order bits.
The decoder (for Alpha) uses the 32nd bit in order to determine if the machine is in PAL mode. If it is, then it refers to the reg_redir table to determine the true index of the register it is using.
Also include the opcdec instruction definition.
arch/alpha/isa_traits.hh:
Define ExtMachInst type that is used by the static inst in order to decode the instruction, given the context of being in pal mode or not.
Redefine the number of Int registers, splitting it into NumIntArchRegs (32) and NumIntRegs (32 + 8 shadow registers).
Change the dependence tags to reflect the integer registers include the 8 shadow registers.
Define function to make an ExtMachInst. Currently it is somewhat specific to Alpha; in the future it must be decided to make this more generic and possibly slower, or leave it specific to each architecture and ifdef it within the CPU.
arch/isa_parser.py:
Have static insts decode on the ExtMachInst.
base/remote_gdb.cc:
Support the automatic remapping of shadow registers. Remote GDB must now look at the PC being read in order to tell if it should use the normal register indices or the shadow register indices.
cpu/o3/regfile.hh:
Comment out the pal registers; they are now a part of the integer registers.
cpu/simple/cpu.cc:
Create an ExtMachInst to decode on, based on the normal MachInst and the PC of the instructoin.
cpu/static_inst.hh:
Change from MachInst to ExtMachInst to support shadow register renaming.

arch/alpha/isa/fp.isa:
Change accesses to IPRs and Fpcr to go through the misc regs.
arch/alpha/isa/main.isa:
Add support for all misc regs being accessed through readMiscReg() and setMiscReg(). Instead of readUniq and readFpcr, they are replaced by calls with Uniq_DepTag and Fpcr_DepTag passed in as the register index.
arch/alpha/isa_traits.hh:
Change the MiscRegFile to a class that handles all accesses to MiscRegs, which in Alpha include the FPCR, Uniq, Lock Addr, Lock Flag, and IPRs.
Two flavors of accesses are supported: normal register reads/writes, and reads/writes with effect. The latter are basically the original read/write IPR functions, while the former are normal reads/writes.
The lock flag and lock addr registers are added to the dependence tags in order to support being accessed through the misc regs.

CPU_MODELS parameter. For example:
scons CPU_MODELS="SimpleCPU,FullCPU" ALPHA_SE/m5.debug
Unfortunately the option is not sticky due to a scons
bug with saving & restoring ListOption parameters.
SConscript:
Separate out cpu-model-specific files so they can be conditionally
included based on value of new CPU_MODELS parameter.
Most of these are now handled in cpu/SConscript, except for FullCPU
which is still in this file.

The set of CPU-model-specific execute files must now be
determined from the CPU_MODELS parameter, via the new
