Let's start adding ':end' labels in all functions, just because it helps
us visualize where function calls end in traces, thanks to the '--map'
commandline argument.
Crenshaw compiler now runs natively as well.
It turns out I was misreading the Intel manual, and the jump instructions
that I thought take disp16 operands actually take disp32 operands by default
on both i686 and x86_64 processors. The disp16 versions are some holdover
from the 16-bit days.
This was the first time I've used one of these erstwhile-disp16 instructions,
but I still haven't tested most of them. We'll see if we run into future
issues.
Start with an exactly corresponding version to Crenshaw 2-1: single-digit
numbers. The only change: we assume the number is in hex.
The next version now supports multi-digit hex numbers.
