 Allow :info for (~) in GHCi

 `(~)` is not an identifier according to GHC's parser, which
 is why GHCi's `:info` command wouldn't work on it. To rectify this,
 we apply the same fix that was put in place for `(->)`: add `(~)` to
 GHC's `identifier` parser production.

 Test Plan: make test TEST=T10059
