Move script to create a Linux-based boot image into a sub-directory.

Move script to create a Soso boot image into a sub-directory.
I'm trying to streamline newcomer attention to just a couple of use cases.

Rename a few scripts to be more consistent.
I'm also starting to feel the urge to bud off `subx run` into its own program,
say tools/emulate_x86. It doesn't really rely on the SubX notation at all.
And then I could rename `subx translate` to `translate_subx_bootstrap`.
Only problem: the commands in the Readme get verbose. But the Readme is
gonna need surgery soon anyway to put translate_mu front and center.

I can now run this program:
fn main -> result/ebx: int {
result <- do-add 3 4
}
fn do-add a: int, b: int -> result/ebx: int {
result <- copy a
result <- add b
}
We still can't define local variables, but can write any programs involving
ints by passing in enough arguments for temporaries.

Let's start putting r32 first in compare instructions that need it. Ordering
there is quite subtle and of great import.

Extremely crappy syntax highlighting for Emacs. I just can't wrap my head
around elisp, and I'm inclined to blame elisp. Checking this off my todo
list and moving on.

Bugfix.

We haven't implemented it yet, but there's now a design for how we check
whether a function has written its output correctly. Functions must write
to each output at the top level at least once, and never overwrite an output
register in the top-level once it's been defined.
This is conservative (it can be perfectly reasonable for functions to write
the output, reuse the register for a temporary, and then write the output
again) but easy to check.

Bugfix: statements defining a new register variable require an initializer
instruction.

Copy (mov) instructions are unlike instructions we've encoded so far, in
that their destination is not read.

One test failing. It took enough debugging just to get to the expected
failure that it seems worth saving this snapshot.
Saw some signs that I have to remember to zero-out allocated memory. We
need a scalable solution for this.
I think parse-var-with-type needs to be rewritten. Just added a test and
a hacky fix for now.

Minor tweaks to stop wasting horizontal space in the trace.

The problem: when I hit 'G' to go to the bottom of the trace, if the bottom
is visible on screen, the screen scrolls so the bottom of the trace
is the bottom-most line on screen. But the cursor moves to where the trace
used to end rather than the new location of the bottom of the trace (the
bottom of the screen).
