label offset computation still has a bug
...
I changed the test a little to make it obvious.
Basically there's no way we can compute the segment offset correctly
without knowing the segment name in the previous assertion.

revert compute-offsets to segment-relative offsets
...
The pseudocode was a mess here :/ I was saving the segment-offset but
tracing the file-offset.
Segments need file offsets (to tweak their starting address).
Labels need segment offsets (to add to segment starting address).

Some nooks and crannies will need light final debugging with xxd, but
emit-hex-output covers most of the logic.

this looks like a bug
...
But of course the test is still infinite-looping so we can't be sure.
I'm still just reading the code.

It's ugly to have function locals in global variables, but we'll figure
out later how to deal with it.

useful to have around.

there's a variant of get-or-insert for slices

The compute-offsets test now goes into an infinite loop :( But I figure
all these changes are useful anyway, we should just debug the error
separately.
