Hah. I was setting up LLVM buildfarm animals that run with LLVM
assertions enabled, and was getting confused why they're failing after
I'd run a check-world locally with assertions enabled.
Turns out this broke it. I'll fix it. Just amazed that we've gone weeks
without a change breaking my JIT work, and then within hours of it
getting it got broken. Turns out LLVM represents a stdbool.h boolean as
an i1 (int with 1 bit) rather than an i8 (int with 8 bits), which makes
sense given the desired boolean behaviour (still takes 8 bits of
storage).
