vm: add standalone JIT

The old JIT's dependency on Lua and DynASM made it a little harder to integrate
with a larger project. Worse, DynASM has bugs that prevented us from using the
using the exact instruction we needed and forced us to fall back to a longer
instruction sequence (STXB/LDXB/BSWAP).

The main disadvantage is readability since we're now writing machine code
instead of assembly. The new JIT isn't (yet) able to emit short 8-bit jump
offsets.
