Changes made in dsp/fourier/internal/fftpack break the formatting used
there, so these are reverted. There will be complaints in CI.

L2 Distance kernel is a slight modification of the L2 Norm kernel,
taking two vectors and calculating the difference before summing squares.
Same overflow protections as the netlib form of the norm calculation.
Netlib algorithm reduces overflow while calculating the l2norm of a
vector.
Translated incremented vector calculation to asm while reducing
branches in NaN and Inf checks. Overflow protection is equivalent to
the Netlib standard implementation.
