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.
