Backends avx2 and ifma do not compile on Zen 2 AMD Ryzen processors

[MarkusZoppelt]

Probem:

I was trying to use backend features by running:

cargo build --no-default-features --features "std simd_backend"

but cannot compile packed_simd on my AMD Ryzen 3900X. My CPU inf (+flags) is listed below the compile log.

Possible fix:

I noticed that the error is related to packed_simd v0.3.3.
If I use the current HEAD (v.0.3.4) from https://github.com/rust-lang/packed_simd, I do not get any errors.

Error messages:
