A little more resizing of buffers. apps/hex.subx is now building an
identical binary.
I'm now aborting on allocation failures. That requires disabling
a couple of tests. (I'm not quite confident enough of this decision to
delete them outright.) I want to treat all segfaults as bugs, and
machine code is no place to add boilerplate checks for return values of
standard library functions.

Clean up. All apps now translating correctly except for the phases of
the self-hosted translator. Next step: SubX-in-SubX in SubX-in-SubX.

Translates 5k lines of input in 26 seconds.
I'm not sure why I need to grow the label table. It was already 512 entries
long, and I'm only using 373 so far.

We can now translate layers 49-72 using the self-hosted translator.
The translator has now demonstrated translation over 4k lines. Most verbose
phase output is 325KB, even if the final binary is 15KB.
Emulation is too slow now, so I'm back to debug by print on a Linux machine.

We can now translate layers 49-56 using the self-hosted translator
(`translate` and `ntranslate`).
As a follow-up to commit 5404, the self-hosted translator is a little
more strict than the C++ translator in 3 places:
a) All .subx files must define a data segment.
b) All .subx files must define an `Entry` label.
c) All numbers must be in *lowercase* hex.
In all cases, where programs work with the C++ translator but violate
the self-hosted translator's assumptions, we must make sure we raise
errors rather than silently emit bad code.

Break a dependency from `print-int32` to `from-hex-char`.

We now have a new pass called 'tests' which code-generates a new
function called 'run-tests', just like the C++ layer `tests.cc`.
