Remove user-selectable ANALYZE option for range types.

Browse Source 
It's not clear that a per-datatype typanalyze function would be any more
useful than a generic typanalyze for ranges.  What *is* clear is that
letting unprivileged users select typanalyze functions is a crash risk or
worse.  So remove the option from CREATE TYPE AS RANGE, and instead put in
a generic typanalyze function for ranges.  The generic function does
nothing as yet, but hopefully we'll improve that before 9.2 release.
