96035f78ec 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.

f237e064fc 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.

4e1ef9c972 translate netlib l2norm algorithm to asm and remove branches 
Netlib algorithm reduces overflow while calculating the l2norm of a
vector.

Translated to asm while reducing branches in NaN and Inf checks.
Overflow protection is equivalent to the Netlib standard implementation.

e2ba7f0950 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.

17ea55aedb blas,lapack: clean up docs and comments 
Apply (with manual curation after the fact):
* s/^T/U+1d40/g
* s/^H/U+1d34/g
* s/, {2,3}if / $1/g

Some additional manual editing of odd formatting.
