This patch enables Cranelift as a compiler for wasm on AArch64 targets. It
also tracks some minor interface changes in Cranelift, since SM needs the
latest cranelift sources to fully support wasm SIMD. This patch will need to
land at the same time as a patch that bumps the vendored-in CL version.
As a ridealong fix, CraneliftContext::threads_enabled is now initialised in
CraneliftContext:: CraneliftContext. It appears to have been uninitialised
until now.
