Alex Crichton 2d25db047f x64: Lower SIMD requirement to SSE4.1 from SSE4.2 (#6206) 
Cranelift only has one instruction SIMD which depends on SSE4.2 so this
commit adds a lowering rule for `pcmpgtq` which doesn't use SSE4.2 and
enables lowering the baseline requirement for SIMD support from SSE4.2
to SSE4.1.

The `has_sse42` setting is no longer enabled by default for Cranelift.
Additionally `enable_simd` no longer requires `has_sse42` on x64.
Finally the fuzz-generator for Wasmtime codegen settings now enables
flipping the `has_sse42` setting instead of unconditionally setting it
to `true`.

The specific lowering for `pcmpgtq` is copied from LLVM's lowering of
this instruction.

This crate performs autodetection of the host architecture, which can be used to configure Cranelift to generate code specialized for the machine it's running on.
