lsp/source: create zero value ast.Exprs

In support of https://golang.org/cl/224960, add utility functions that
create zero value expressions for a given types.Type. There are probably
some bugs here but they pass the basic tests in that CL.

Known problems: it skips through type aliases, and can't handle
anonymous structs/interfaces. Hopefully it's pretty unusual to return
those.
