Running wasmtime demo fails when built with cg_clif

[vi]

If built with rustc_codegen_cranelif's Cargo wrapper, wasmtime's "Hello world" (with wasmtime = "0.36.0") outputs:

Error: compilation settings are not compatible with the native host

Caused by:
    compilation setting "has_sse3" is enabled but not available on the host

If I use usual Cargo, I get:

Answer: 42

cg_clif's Rust version: cargo 1.62.0-nightly (a44758ac8 2022-05-04), repo version: 343c532.
Usual Rust version: cargo 1.63.0-nightly (a4c1cd0eb 2022-05-18).

Try using the main branch of wasmtime and I think disabling support for the simd wasm feature. Cg_clif fakes a cpuid output to disable most target features as the corresponding intrinsics aren't implemented yet. Wasmtime requires sse4.1 I believe when simd support is enabled. Also there was recently a fix for wasmtime requiring sse4.1 even when simd support is disabled. This fix isn't yet included in any released version of wasmtime

If you comment out https://github.com/bjorn3/rustc_codegen_cranelift/blob/c3a0431731e399b22670f83a7796649e50abd1b0/src/inline_asm.rs#L53-L132 it gets past this check but hits https://github.com/bjorn3/rustc_codegen_cranelift/issues/1381.

Fixed in 55380a5. The entire wasmtime test suite passes now with the exception of the tests that test panics as cg_clif doesn't yet support unwinding on panics.
