function into Alpha ISA description. write now just generically
returns a result value if the res pointer is non-null (which means
we can only provide a res pointer if we expect a valid result
value).

We don't currently use randomness much, so I didn't go too far, but
in the future, we may want to actually expose the random number values
themselves to python. For now, I'll at least let you seed it.
While we're at it, clean up a clearly bad way for generating random
doubles.

access to enabling/disabling tracing. Command line is
unchanged except for the removal of --trace-cycle since
it's not so clear what that means.

that made ccprintf and friends work, turn it into a
normal function (though it still has a slightly strange
implementation.) All instances of variadic macros
are not yet removed, but I know how, and it will happen.
One side effect of this new implementation is that a
cprintf statement can now only have 16 parameters, though
it's easy enough to raise this number if needed.

Created MemCmd class to wrap enum and provide handy methods to
check attributes, convert to string/int, etc.

Caveats:
- Even though memtest is ISA-independent, it will only
run for the Alpha builds, since there's no way to specify
ISA-independent reference files and I didn't want to commit
3 copies since I'm not sure we want to run it for all the
different ISAs anyway.
- Reference outputs were generated on my laptop,
so performance numbers will be low compared to zizzer.

fix unaligned accesses in mmaped disk device
src/arch/sparc/isa/decoder.isa:
get (ld|st)fsr ops working right. In reality the fp enable check needs to go higher up in the emitted code

move the cexec into the aexec field
src/cpu/exetrace.cc:
copy the exception state from legion when we get it wrong. We aren't going to get it right without an fp emulation layer
