I've built YoWASP nextpnr with parallel refinement enabled and I can report that the improvements running on wasmtime are very similar to those seen with a native build.

@whitequark, thanks for this PR! I am fine with this but I feel like @sunfishcode should take a look: do we want to merge this in main? I think it makes sense to do so, but it is related to the decision on whether the wasi-sdk-20 — the real release, not my pre-release — contains all of the wasm32-wasi-threads target stuff. I would assume yes, but wanted to leave it up to you. (Once this is merged, I could patch it into #296 and rebuild the wasi-sdk-20+threads pre-release with this to try things out).

wasilibc: 19 -> 20

pkgsCross.wasi32.llvmPackages: 12 -> 16

* It appears BULK_MEMORY_SOURCES no longer needs to be set to be empty
  to compile firefox. Without it, the build of wasilibc would fail if
  enableThreads is true.

* Include preliminary support for the experimental threads support in
  wasilibc which provides pthreads API. If wasilibc is built with
  support, is exposed via passthru and libcxx / libcxxabi are built with
  threads support accordingly.

  wasi-sdk ships it by default, but as a separate variant of libc which
  would be a hassle for us. Let's just make it optional for now.

  You can try it out using the following overlay:

      self: super: {
        wasilibc = super.wasilibc.override { enableThreads = true; };
      }

  Flags for libc++abi are copied from wasi-sdk.
