f78bc80bd7 Move store conditional result checking from SimpleAtomicCpu write
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).

63a8240059 Get rid of the Random context and add the support directly to python.
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.

1f834b569c Get rid of the gross operator,()/variadic macro hack
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.

d486700149 Add short memtest run to quick regressions.
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.
