5897 - rename comparison instructions

Signed and unsigned don't quite capture the essence of what the different
combinations of x86 flags are doing for SubX. The crucial distinction is
that one set of comparison operators is for integers and the second is
for addresses.

Binaries are now identical again.
There's a little hack here that we should clean up at some point. But it
requires more thought.
Ordering compiler phases is hard. So far we're only at the start of the
slippery slope into that abyss.

It's always seemed ugly to explain the rules for segment names. Let's just
always require a fixed name for the code and data segments.

Finally really fix the CI failure of commit 4894.
This is a remainder to forget my knowledge of stack addresses in the SubX
VM when writing SubX programs. Otherwise my programs will work in the VM
but not natively. The only assumptions a SubX program should make about
its segment addresses are what's encoded in the ELF binary. Thanks to
https://en.wikipedia.org/wiki/Address_space_layout_randomization , it can't
know anything else.

Couple more tweaks to html rendering:
a) SubX definitions no longer link redundantly to themselves. This long-standing
issue turns out to be tractable to solve for SubX files since the syntax
is so simple.
b) Fix links to SubX definitions in other directories. I forgot that I
have to always generate tags from the directory of the file being linkified.
c) Fix link colors. Before we lost all syntax highlighting for functions
and Globals. Now they maintain their colors, just add an underline.

2. pack and reorder operands
3. compute label addresses

Clean up a few things:
a) Call scan-next-byte in hex.subx with the right number of args. Turns
out tests continue to work fine if they never use the other args.
b) Tear down a test for 'stop' in the right order. Not important since we
have no EBP to restore. But can still be misleading.
c) Have 'check-ints-equal' return nothing. Handy for it to not mess up
EAX. I never use the result anyway, and the name also is imperative suggesting
callers won't expect a return value.

I was 'returning' a phantom value from 'write' when the underlying '_write'
returns nothing.
In general, returning counts of bytes written is not so useful for error
checking when my primitives abstract away from that. We'll come back to
error signalling later.
