84aa2fad2d . 
Fix infinite loop in the 2 remaining failing tests; now it's a segfault.

48aabc860a mostly done with emit-output 
Some nooks and crannies will need light final debugging with xxd, but
emit-hex-output covers most of the logic.

20a527702b done with emit-segments 
Only failures now are the first two tests in survey.subx.

f6ea25613f preserve truthiness of non-booleans 
Everywhere we check if something is true, we check it by comparing
against 0, not 1.

7a752f8d3d 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.

ba93234603 move 'segment-start' to a global variable as well 
It's ugly to have function locals in global variables, but we'll figure
out later how to deal with it.

dc7066c7bf there's a variant of compute-width for slices 
Looks like the original compute-width is now dead. But still seems
useful to have around.

acc83b644b 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.

Be more consistent about names of ends of a slice.
(In the opposite direction compared to last night's 925fc490d2ce8b8d411de87bd0af5b3a8a704213.)

fb8474af88 new failing test: emit-segments

Make `compute-addresses` less clever. Stop striding from the middle of
one row to the next. This way we'll also obviate the need for indexing
backwards from a pointer in the next commit.

120a740871 some primitives for emitting traces 
Kinda hacky, but might scale enough for machine code.

This was really hard to debug. Single tests passed, but when I ran all
tests I got breakage because tests long before (from the 056trace layer)
were not cleaning up properly.

My instinct was to call clear-stream on Trace-stream, which was wrong
(the trace didn't have the wrong contents, it was literally a bad
object). It was also wrong in a counter-productive way: calling
clear-stream on a real Trace stream (which is the size of a page of
memory) takes a long time in emulated mode.
