cmd/compile, go/parser: disallow "type T = p.T" - must use "=>"
I had added this originally so we can play with different notations
but it doesn't make sense to keep it around since gofmt will convert
a type alias declaration using "=" into one using "=>" anyhow. More
importantly, the spec doesn't permit it.
