Yes, and that's because there's only a `real` version for fmax.
If upstream Phobos had proper double/float overloads, we could
uncomment the LDC-specific implementations using LLVM intrinsics,
which use (obviously much faster) SSE instructions:
Number crunching in D could be significantly accelerated if the
people interested in it showed some love for std.math, but we've
had this topic for years.
