Avoid NEON SP-FP unless unsafe-math or Darwin NEON is not IEEE 754 compliant, so we should avoid lowering single-precision floating point operations with NEON unless unsafe-math is turned on. The equivalent VFP instructions are IEEE 754 compliant, but in some cores they're much slower, so some archs/OSs might still request it to be on by default, such as Swift and Darwin. llvm-svn: 177651
