asm/f64: add asm implementation of l2distance function
...
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.

asm/f64: translate l2norm with increment to asm
...
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.

internal/asm,blas,floats: move level 2 norm to asm
...
This allows sharing of the blas implementation with floats and opens the
possibility of an assembly implementation of this function.

* s/^H/U+1d34/g
* s/, {2,3}if / $1/g
Some additional manual editing of odd formatting.
