Reviewed by Justin Michaud.

Adds support for WebAssembly SIMD instructions to the new single-pass BBQ baseline JIT.
Mostly mimics the Air implementation, but does the Air lowering macros inline since we
directly call out to the macro assembler.

The new baseline JIT is still disabled by default, since it fails quite a few of our
stress tests. It's not yet ready for typical usage. But with this patch, we at least
expect that the SIMD (and core) spec tests will pass on ARM64 and x86_64.
