To support this, also renamed (read|write)[1248] on memory_object and

the interface can remain virtual). I did not do that though.

cpu/checker/cpu.cc:
Cleanup checker, give more useful warning messages.
Also fix bug
cpu/checker/cpu.hh:
Cleanup checker, use forward declaration instead of include.

arch/alpha/ev5.cc:
Move kernel stats out of CPU and into XC. Also be sure to check if the kernel stats exist prior to using them.

IsIprAccess flag may go away in the future (op class can be used to tell this), and the CPU still needs a specific way to identify/deal with syscalls.
arch/alpha/isa/decoder.isa:
Added a few extra flags to help the new CPU identify various classes of instructions without having to force certain behaviors for all CPUs.
cpu/base_dyn_inst.hh:
cpu/static_inst.hh:
Added extra flags.
cpu/o3/iew_impl.hh:
cpu/o3/inst_queue_impl.hh:
Handle store conditionals specially.
cpu/o3/lsq_unit_impl.hh:
Extra flags tells if the instruction is a store conditional.
cpu/o3/rename_impl.hh:
Handle IPR accesses and store conditionals specially.

Undo changes to allow multiple build roots in a single
invocation... this would have been too messy to maintain
with the auto-configure stuff, and probably isn't useful anyway.

It doesn't compile, and if we really want this we should
start over from scratch and see if we can reuse parts from
BaseSimpleCPU (e.g., derive a FastSimpleCPU).
SConstruct:
src/arch/SConscript:
src/cpu/cpu_models.py:
Get rid of FastCPU model.

src/arch/sparc/isa/formats/nop.isa:
Fix nop header so we can compile with multiple CPU models.
(Former code re-defined Nop object for each model.)

SConstruct:
Clean up libelf handling. Required better handling of
per-build-root stuff in general (though libelf is the
only thing in that category currently).
src/SConscript:
No libelf-specific stuff in here anymore.
src/base/loader/elf_object.cc:
Just need to include gelf.h... it includes libelf.h.

This temporarily will break the O3 and Ozone CPU models. Updates to fix them will be coming soon.
arch/alpha/isa/decoder.isa:
Undo changes to instruction flags that has caused statistics to change in regressions.

cpu/SConscript:
Remove sat_counter.cc and push its functions into the .hh file (all functions were 3 or less lines).
cpu/o3/sat_counter.hh:
Incorporate .cc code into this file.

Dependecy graph code moved into its own class.
This requires the changes to the functional units, which is in the next check in.
cpu/o3/iew.hh:
cpu/o3/iew_impl.hh:
IEW and IQ code cleanup and reorganization.
cpu/o3/inst_queue.cc:
Dependency graph code moved into its own class now.
cpu/o3/inst_queue.hh:
IEW/IQ code cleanup and reorganization.
Dependecy graph code moved into its own class.
cpu/o3/inst_queue_impl.hh:
IEW/IQ code cleanup and reorganization.
Dependecy graph code moved into its own class.
Issue loop cleaned up, with completion events for functional units now used more correctly (before they weren't used for multi-cycle ops with pipelined FU's).
