This patch pulls in Cranelift revision 47a218f908e6bdeb7a0fb65ed74e58a0b608080d, which incorporates several relevant changes: - It includes the Spectre mitigation for explicit heap bounds checks merged in PR bytecodealliance/wasmtime#1930, resolving Bug 1648885. - It includes the fix for an out-of-bounds subtraction on large shift amounts merged in PR bytecodealliance/wasmtime#1954, resolving Bug 1649432. We need to temporarily disable the `wasm/limits.js` jit-test on Cranelift configurations because it now needs shared memory to work, and the Cranelift backend does not support this yet. Given that this should be ready in the next month at most (requires atomics support on AArch64, which is currently being examined), it seems simpler to temporarily disable the test on aarch64 than to try to disentangle the bits that depend on shared memories explicitly. This patch also edits the `regexp/bug1445907.js` jit-test to run only if Wasm debugging is supported. This is needed for the test not to fail with `--wasm-compiler=cranelift` (which disables Baseline, the only Wasm compiler that supports debugging).
