  Pass core WebAssembly spec tests on ARM64 with single-pass WebAssembly baseline JIT

Reviewed by Yusuke Suzuki.

Adds a new single-pass baseline JIT implementation for WebAssembly, the single-pass
BBQ JIT. The main goal of this new compiler is to compile substantially faster than
the existing Air tier, while offering comparable levels of generated code performance.
This should help us start up considerably faster on large WASM programs.

This is the initial commit of this feature, and the new baseline is only partially
complete. Currently, it should pass all the core spec tests on ARM64, but there are
some remaining issues on other platforms, some failures on the full stress tests, and
missing support for some key features like SIMD. As such, it's being landed disabled
by default, behind the new '--useSinglePassBBQJIT' flag.
