Panic if AVX or FMA is missing #119

Closed cevian closed 3 months ago

cevian commented 3 months ago

Our compilation on x86 enables fma and avx in target-feature. We should panic if the running CPU is actually missing the feature because otherwise the behavior is undefined and in practice we've seen segfaults.

The panic will be translated to a Postgres error.
