output source files to (in theory) reduce compilation time.
arch/alpha/isa_desc:
Update for parser changes. Move most constructors
out of class declarations (which are now in decoder.hh)
and into decoder.cc. Move all execute() methods into
exec output.
arch/isa_parser.py:
Significant changes to make ISA description completely
independent of CPU model, and isolate model-dependent parts
of parser into one little class (CpuModel). Also split up code
output into multiple files (a header, a main source file, and
per-cpu execute() method files).
Noticeable changes to language as a result. See updated Doxygen
documentation.

SimpleCPUExecContext typedef no longer needed.

This replaces the scalar() and functor() terms that were
previously used in formulas. This helps when dumping
statistics because the formulas are not supposed to change.

base/statistics.hh:
major changes to the statistics package again
lots of code was factored out of statistics.hh into several

There are now two Stat package types Result and Counter that
are specified to allow the user to keep the counted type
separate from the result type. They are currently both doubles
but that's an experiment. There is no more per stat ability to
set the type. Statistics::Counter is not the same as Counter!
Implement a visitor for statistics output so that new output
types can be implemented independently from the stats package
itself.
Add a unique id to each stat so that it can be used to keep
track of stats more simply. This number can also be used in
debugging problems with stats.
Tweak the bucket size stuff a bit to make it work better.

configuration unnecessarily awkward. Biggest changes are:
- External and internal object names now match in all cases. The
macros still allow them to be different; the only reason I didn't
get rid of that is that the macros themselves should be going away
soon. In the few conflicting cases, I sometimes renamed the C++ object
and sometimes renamed the config object. The latter sets of substitions
are:
s/BaseBus/Bus/;
s/MemoryObject/FunctionalMemory/;
s/MemoryControl/MemoryController/;
s/FUPool/FuncUnitPool/;
