Miri already supports a lot of intrinsics: https://github.com/rust-lang/miri/tree/master/src/intrinsics so I think it make sense to return
truefor compile time enabled features, so if someone runsRUSTFLAGS=+avx2 cargo miri runit will actually enable those features, as the user explicitly asked for themAlso added tests to show that it works outside and inside of miri
tested everything locally too(including loongarch64 via qemu)
