Wasm translator multi-value bugfix: handle branch to loop with loop parameters.

59307625c8 Allow ModuleTranslationState to be constructed with signatures. 
This is needed to allow SpiderMonkey to provide function signature types
to the wasm translator when it uses Cranelift as a backend without
using the wasm translator to parse the entire module. There is perhaps a
better long-term design here where we allow an embedding that already
parses the Wasm module (such as SpiderMonkey) to provide information in
a more principled way, this suffices for now.

Patch is inspired by Ben's patch in
https://bugzilla.mozilla.org/show_bug.cgi?id=1641504, but does not
expose `wasmparser` types directly, instead using Cranelift types across
the API boundary.

bc555468a7 cranelift: add i64.{ishl,ushr,ashr} libcalls. 
These libcalls are useful for 32-bit platforms.

On x86_32 in particular, commit 4ec16fa0 added support for legalizing
64-bit shifts through SIMD operations. However, that legalization
requires SIMD to be enabled and SSE 4.1 to be supported, which is not
acceptable as a hard requirement.

63a335b7d4 Avoid touching encodings in EncCursor if using a MachInst backend. 
`EncCursor` is a variant of `Cursor` that allows updating CLIF while
keeping its encodings up to date, given a particular ISA. However, new
(MachInst) backends don't use the encodings, and the `TargetIsaAdapter`
shim will panic if any encoding-related method is called. This PR avoids
those panics.

Fixes #1809.

1ea09088be Add x86 legalization for imul.i64x2 for non-AVX CPUs 
The `convert_i64x2_imul` custom legalization checks the ISA flags for AVX512DQ or AVX512VL support and legalizes `imul.i64x2` to an `x86_pmullq` in this case; if not, it uses a lengthy SSE2-compatible instruction sequence.

df171f01b5 Add x86_pmuludq 
This instruction multiplies the lower 32 bits of two 64x2 unsigned integers into an i64x2; this is necessary for lowering Wasm's i64x2.mul.

9ba9fd0f64 Add x86-specific instruction for i64x2 multiplication 
Without this special instruction, legalizing to the AVX512 instruction AND the SSE instruction sequence is impossible. This extra instruction would be rendered unnecessary by the x64 backend.
