The compiler is incorrectly rejecting switches on arrays of
comparable types. It also doesn't catch incomparable structs
when typechecking the switch, leading to unreadable errors
during typechecking of the generated code.

Fixes #3894.

for dealing with CLDR files:
- Add now taxes a list of indexes of colelems that are variables. Checking and
  handling is now done by the Builder.  VariableTop is now also properly generated
  using the Build method.
- Introduced separate Builder, called Tailoring, for creating tailorings of root
  table.  This clearly separates the functionality for building a table based on
  weights (the allkeys* files) versus tables based on LDML XML files.
- Tailorings are now added by two calls instead of one: SetAnchor and Insert.
  This more closely reflects the structure of LDML side and simplifies the
  implementation of both the client and library side.  It also preserves
  some information that is otherwise hard to recover for the Builder.
- Allow the LDML XML element extend to be passed to Insert.  This simplifies
  both client and library implementation.

This is more in sync with the rest of the package;
for instance, we have functions (not methods) to
deref or find the underlying type of a Type.

If an end tag has an attribute that is a quoted string containing '>',
the tokenizer would end the tag prematurely. Now it reads the attributes
on end tags just as it does on start tags, but the high-level interface
still doesn't return them, because their presence is a parse error.

To be filled in by a later CL. I deployed a test version to
App Engine to work on setting the values, so there are
a few records that have this field set already.

That field is breaking the live version, so I have pushed
a new copy with this 1-line change to the live version

I assumed that appengine/datastore was like every other
marshaling and unmarshaling package we have in Go
(for example, encoding/gob, encoding/json, encoding/xml,
and protobuf) and that if it loaded an unknown field it would
just ignore it. Apparently not. Sorry.
