cpu/beta_cpu/commit_impl.hh:
Formatting changes mainly. Also sends back proper information
on branch mispredicts so that the bpred unit can update itself.
Updated behavior for non-speculative instructions (stores, any
other non-spec instructions): once they reach the head of the ROB,
the ROB signals back to the IQ that it can go ahead and issue the
non-speculative instruction. The instruction itself is updated so that
commit won't try to commit it again until it is done executing.

how it loops through groups of instructions so it can properly block

- Add support for binning kernel/user/idle time separately from
lisa's binning stuff, but make the two compatible.

- Factor common code out of LinuxSystem and Tru64System and put
it into the System base class. While doing that, make all

Also various changes to make the CPU model less ISA dependent, which includes moving the code that checks for interrupts up to the ISA level, moving code that zeroes the zero registers up to the ISA level, and removing opcode and ra from the regfile.
arch/alpha/alpha_memory.cc:
The regfile has been changed so it no longer has the opcode and ra. Instead the xc holds the actual instruction, and from there the opcode and ra can be obtained with OPCODE() and RA().
arch/alpha/ev5.cc:
Moved code that once existed within simpleCPU to ev5, and templatized it.
This way the CPU models can call processInterrupts and the ISA specific interrupt handling is left to the ISA's code.
Also moved ISA specific zero registers from simpleCPU to here.
arch/alpha/ev5.hh:
Added macros for obtaining the opcode and ra from the instruction itself, as there is no longer opcode or ra in the regfile.
arch/alpha/isa_desc:
Added in declarations for the FastCPU model.
arch/alpha/isa_traits.hh:
Removed opcode and ra from the regfile. The xc now holds the actual instruction, and the opcode and ra can be obtained through it.
Also added the declaration for the templated zeroRegisters() function, which will set the zero registers to 0.
arch/isa_parser.py:
Added in FastCPUExecContext so it will generate code for the FastCPU model as well.
cpu/exec_context.cc:
Added in a more generic trap function so "ev5_trap" doesn't need to be called. It currently still calls the old method, with plans for making this ISA dependent in the future.
cpu/exec_context.hh:
Exec context now has the instruction within it. Also added methods for exec context to read an instruction from memory, return the current instruction, and set the instruction if needed.
Also has declaration for more generic trap() function.
