Sam Harwell d0cd250634 Remove the shared visitor tests 
These tests were modeled after the listener tests, but were not implemented
against the standard visitor API semantics. The tests only execute in the
Node.js target, and there is no straightforward way to implement these tests
across multiple targets. New tests which cover both the traversal behavior
and the runtime semantics are now available and should be implemented by
each target.

Sam Harwell eb53e70e39 Implement support for optional getters 
This analysis is required for proper code generation in the TypeScript target
when strict null checks are enabled. It also applies to targets intending to
differentiate optional values from required values.

Terence Parr b57843d983 Merge pull request #1546 from sharwell/fix-1545 
Fix multiple problems with optional block bypass at end of rule
 2016-12-27 21:47:12 -08:00
Sam Harwell 24b20e236f Remove redundant isExpectedToken check 
We know by the time this check was reached that neither EPSILON nor the LL(1)
symbol are in the lookahead set from the current state. Since EPSILON is not
included, the state cannot see to the end of the rule and thus nextTokens
contains the complete set of valid LL(1) symbols from the current state. It is
therefore impossible for the LL(1) symbol to be "expected" when considering
lookahead with full context.

Mike Lischke ad31b44009 Removed static libraries from deployment script (Windows). 
Static libs are huge, so they put quite some burden on download management. They are easy to create from source, however.
