Versions of Go whose testing package doesn't yet support subtests and
sub-benchmarks are no longer supported. Drop an intermediate layer of
compatibility from the ./internal/texttest package.

The initial version of this change was git-generate'd with the script:

rm internal/testtext/go1_{6,7}.go
gofmt -r 'testtext.Run(t, n, f) -> t.Run(n, f)' -w .
gofmt -r 'testtext.Bench(b, n, f) -> b.Run(n, f)' -w .
goimports -w .

Unfortunately it seems gofmt -r dropped inner comments inside f, and
also added some spurious blank lines. So it was manually amended not
to include those changes.

These days people will just import the packages and the go tool will
do the right thing. We don't need to explain it.

Add a pointer to the git repo, though.
