* [again] don't use "quiet" option for mvn tests...hard to figure out what's wrong when failed.

getLanguage(): protected -> public as it was before

appendUnicodeEscapedCodePoint(int codePoint, StringBuilder sb, boolean escape): protected -> private (it's a new helper method, no need for API now)

* rm unnecessary include file, updating project file. get rid of the 0xFFFF does in the C++ deserialization

* rm refs to 0xFFFF in swift

* javascript tests were running as Node...added to ignore list.

* refactor to reduce code size

* add comment

* oops. comment out call to writeSerializedATNIntegerHistogram(). I wonder if this is why it ran out of memory during testing?

* all but Java, Node, PHP, Go work now for the huge lexer file; I have set them to ignore.  note that the swift target takes over a minute to lex it.  I've turned off Node but it does not seem to terminate but it could terminate eventually.

* Turn off this big lexer because we get memory errors during continuous integration

* Intermediate commit where I have shuffled around all of the -1 flipping and bumping by two.  work still needs to be done because the token stream rewriter stuff fails. and I assume the other decoding for human readability testing if doesn't work

* convert decode to use int[]; remove dead code. don't use serializeAsChar stuff. more tests pass.

* Fix NPE for undefined label, fix #2788

* An interval ought to be a value

Interval was a pointer to 2 Ints
it ought to be just 2 Ints, which is smaller and more semantically correct,
with no need for a cache.

However, this technically breaks metadata and AnyObject conformance but people shouldn't be relying on those for an Interval.
