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.

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.
