floating-point sum and product produce incorrect results when NaNs are present #6
Description
Due to https://bugs.llvm.org/show_bug.cgi?id=36732, wrapping_sum / wrapping_product are implemented with fast-math flags unconditionally enabled, which results in inconsistencies like them returning a NaN for which the nan.is_nan() method returns false...
We'll probably need to work-around these issues here in stdsimd.
Now that LLVM7 has been merged we should be able to disable the fast math flags in rust-lang/rust to fix this issue.
