1137dd2a99 tile: process space at start of word 
This was very difficult to debug.

We still need to process space in the middle of a word.

Cursor now updating right.

Still a couple of bugs:
  ctrl-e doesn't know about multiple lines
  function calls don't expand right in multi-line sandboxes
    (but at least I'm now getting to see them in action!)

Defining new functions seems to be working. _However_, we aren't yet detecting
duplicates. `x x *` leads to a declaration of `x x f`.

Rendering is still ugly. Cursor isn't on the right row. But the hard part

This was a stupid mistake in function-body, and it happened because I've
been getting lazy and passing (addr handle) objects when I should be passing
in "constant" addr objects.

I'm not sure why I was so resistant to debugging by print here. I spent
3 days waffling about with this bug.

Snapshot that requires a check in the Mu compiler.

Currently I don't spill a register if it could possibly be over-written
by a function output within. However, find-in-call-path is a good example
of where this constraint is too lenient and results in unsafe code. The
variable `curr` gets clobbered during loop update by the variable `match?`.

What's the answer? Perhaps we should ban all conditional updates to function
outputs? That'd be dashed inconvenient.

The final fix to the raytracing program involves rounding modes. It turns
out x86 processors round floats by default, unlike C which has trained
me to expect truncation. Rather than mess with the MXCSR register, I added
another instruction for truncation. Now milestone 3 emits perfectly correct
results.

cdff5d73ce 6952 - raytracing: much better 
The image is now visually indistinguishable from the baseline, though the
file isn't quite bit-for-bit correct.

I found 3 bugs:
a) I forgot to normalize the ray. After creating a helper to "automatically"
do it for me, it turns out said helper requires manually using.
b) I forgot to multiply by t at one place.
c) vec3-length was half-written.

For the umpteenth time, the bugs were all in the last place I looked. I
was worried about spending a lot of time transcribing `main` without any
feedback, but that turned out to be perfect.

Not yet right, but worth a snapshot just because it gives a cool result.
Here, try it out:
  $ ./translate_mu_debug apps/raytracing/3.mu
  $ ./a.elf > x.ppm
Now view x.ppm as an image.

In general, this was quite tedious to write. And a still-open question
is how to emit the progress bar to stderr. My options are to either duplicate
all my print-* functions (already proliferating) or add global variables
to Mu.

42500e3f47 6932 - another bug related to floats 
For most of Mu's history we've selected between primitives based on types
just by checking whether a type is a literal or not. Now we've started
checking if it's a float as well. However, floats need one additional check:
the call site may have an (addr float) that is dereferenced.

8d32a9aab9 6915 - a new family of Mu branch instructions 
The realization of commit 6916 means that we should be using jump-if-addr*
after comparing floats. Which is super ugly. Let's create aliases to them
called jump-if-float*.

Make a few tests more self-contained.

I'd prefer to just run a function called `setup` first thing on startup
and move this portion of convert-mu to it:
    # initialize global data structures
    c7 0/subop/copy *Next-block-index 1/imm32
    8b/-> *Primitive-type-ids 0/r32/eax
    89/<- *Type-id 0/r32/eax  # stream-write
    c7 0/subop/copy *_Program-functions 0/imm32
    c7 0/subop/copy *_Program-functions->payload 0/imm32
    c7 0/subop/copy *_Program-types 0/imm32
    c7 0/subop/copy *_Program-types->payload 0/imm32
    c7 0/subop/copy *_Program-signatures 0/imm32
    c7 0/subop/copy *_Program-signatures->payload 0/imm32

However, this approach doesn't fix my run_one_test tooling.

a71e5326bd 6827 - tile: make top of stack line up 
Idea from the Future of Software group. I was resistant for several days,
because stacks should grow up, and because it didn't seem like a problem
that the first column's result grew farther and farther away from its input.
But eventually I noticed that the final result can also be arbitrarily
far below, which seems more serious.

This approach also has the salubrious effect of not requiring the precomputation
of max-depth.
