f040f6bd07 all: replace godoc.org README badges with godocs.io ones 
The links have been redirecting to `pkg.go.dev` for a while now. In the
case of the main README, that made the badge a virtual duplicate of the
"go.dev reference" one.

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.

86e8186781 blas/gonum: make drotmg test pass 
This change prevents the compiler from emitting FMA instructions during
Drotmg and Drotm which would otherwise cause the arm64 build to fail.

f41a0d0905 blas/gonum: fix bug in Dsyrk 
The intention of the affected code was an optimization by avoiding
unnecessary multiplication of C when beta == 1. The bug was that the
condition compared beta to 0 instead of 1 (when uplo == blas.Lower)
which behaved correctly for all values except 0. This went unnoticed
since no test case used beta of 0 and the coverage was complete. This
commit fixes the bug and adds test cases for both Lower and Upper values
of uplo.
