Dominik Honnef d5df4d61ce cmd/gofmt: don't turn nil slices into empty slices during rewriting
The go/ast package uses and guarantees nil slices for optional
elements that weren't present in the parsed source code, such as the
list of return values of a function. Packages using go/ast rely on
this attribute and check for nils explicitly.

One such package is go/printer. In the presence of empty slices
instead of nil slices, it generates invalid code, such as "case :"
instead of "default:". The issues that this CL fixes are all
manifestations of that problem, each for a different syntactic
element.

Fixes #33103
Fixes #33104
Fixes #33105
