5f0141ca4c all: run gofmt and generate all packages 
Changes made in dsp/fourier/internal/fftpack break the formatting used
there, so these are reverted. There will be complaints in CI.

[git-generate]
gofmt -w .
go generate gonum.org/v1/gonum/blas
go generate gonum.org/v1/gonum/blas/gonum
go generate gonum.org/v1/gonum/unit
go generate gonum.org/v1/gonum/unit/constant
go generate gonum.org/v1/gonum/graph/formats/dot
go generate gonum.org/v1/gonum/graph/formats/rdf

03398562de all: clean up lint identified by ruleguard 
Ruleguard run with ruleguard -c=0 -rules ruleguard.rules.go ./... from
https://github.com/dgryski/semgrep-go with the following rules inactivated
to reduce noise:

- unconvert for floating point values
- oddcomparisons
- floateq

d1303f035c internal/asm/f64: fix bug and clean up variable names 
The code was jumping to end when tail == 0, but the correct thing is to jump
when LEN is zero. TAIL == 0 means we can start the summing pipeline. We also
don't need to decrement the TAIL since we overwrite it at start of no_trim.

c70431e9bd all: add gccgo build constraint 
This is a synonym for noasm since gccgo (and gollvm) do not use plan9
assembly, so we just prevent those compilers from looking at asm files.

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.
