simd_fmax is broken in LLVM6 #7
Description
See rust-lang/rust#49249, simd_fmax is broken in LLVM6, and the decision there was to work around this in stdsimd until rustc starts using LLVM7. This rust-lang/rust issue tracks that rust-lang/rust#49261
EDIT: now that LLVM7 has been merged simd_fmax should work properly and be used.
