To be more specific:
1) The JS engine should work on any CPU and on most reasonable
operating systems in bytecode mode. It's still pretty fast as bytecode
- nearly an order of magnitude faster than the old WebKit JS engine.
2) Currently the JIT only fully works on x86 and will soon also work
on x86_64 (currently some basic tests pass but neither performance nor
correctness are where we want them to be).
3) We are considering ports of the JIT to other CPU architectures. For
mobile platforms, it's not entirely clear whether the JIT will turn
out to be better than the bytecode interpreter - the memory cost might
outweigh the speed benefit.
