Alex Crichton 709f7e0c8a Enable SSE 4.2 unconditionally (#3833 )

* Enable SSE 4.2 unconditionally

Fuzzing over the weekend found that `i64x2` comparison operators
require `pcmpgtq` which is an SSE 4.2 instruction. Along the lines of #3816
this commit unconditionally enables and requires SSE 4.2 for compilation
and fuzzing. It will no longer be possible to create a compiler for
x86_64 with simd enabled if SSE 4.2 is disabled.

Fuzzing Infrastructure for Wasmtime

This crate provides test case generators and oracles for use with fuzzing.

These generators and oracles are generally independent of the fuzzing engine that might be using them and driving the whole fuzzing process (e.g. libFuzzer or AFL). As such, this crate does not contain any actual fuzz targets itself. Those are generally just a couple lines of glue code that plug raw input from (for example) libFuzzer into a generator, and then run one or more oracles on the generated test case.

If you're looking for the actual fuzz target definitions we currently have, they live in wasmtime/fuzz/fuzz_targets/* and are driven by cargo fuzz and libFuzzer.
