known good revision 52a50509b83b
after bisect, this is the first commit that breaks gofmt -r 'interface{} -> MyType'
(endless recursion)

Comment 2:

after more bisect, this commit is the first for go/parser.ParseExpr to reject
"interface{}".

summary:     go/parser: do not accept type literals where not permitted in general
and sure enough, rev 9440:e7bbaa4eae1f could still properly rewrite
pkg/container/vector/vector.go.
well, this means go/parser.ParseExpr is working as intended.
leaving for gri to decide how to do with "gofmt -r 'interface{} -> MyType'".
IMO, it should be supported, as "gofmt -r 'int -> int8'" is supported, and
rewriting interface{} to some specific type is generally useful for specializing
a generic (interface{}) data type implementation.
