Without this there's no way to convert an int to a byte. And that feels
too restrictive, and gives up a lot of safe things one might want to do
with bytes. (Such as divide a number by 10 and emit the remainder as a
byte.)
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.
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*.
- allocate var
- populate var, n
Both rely on the type of `var` to compute the size of the allocation. No
need to repeat the name of the type like in C, C++ or Java.
