This only removes the ability to build it, and removes it as a
src/buildall.bash target (which uses go tool dist list).

Now:

$ go tool dist list | grep ^darwin
darwin/amd64
darwin/arm64

After this, remaining is removing leftover port--specific code in the
tree.

The darwin/arm port is removed in Go 1.15. Setting GOOS=darwin
GOARCH=arm will fail, therefore "go test cmd/link" on macOS will
fail (in non -short mode). Remove this test point.

The 32-bit pairs darwin/386 and darwin/arm are removed in Go 1.15,
and the master branch is where Go 1.15 is being developed.
The builder has started to fail after CL 226985 (as intended),
so remove it. Keep it running on Go 1.14 and 1.13 release branches.

Also update the misc-compile-darwin builder description.

For golang/go#37610.
For golang/go#37611.
