The recommended way forward is to use the SyntaxClassifier on the Swift
side.
By removing the C++ SyntaxClassifier, we can also eliminate the
-force-libsyntax-based-processing option that was used to bootstrap
incremental parsing and would generate the syntax map from a syntax
tree.
The existing libSyntax infrastructure uses external python
dictionaries to share logic between C++ and Swift implementations.
This patch teaches trivia kinds to adapt to this infrastructure
as well.
Make the quoted parameters more portable. This is needed in order to
support building swift on Windows. Simplify the declaration of the
flags and do a small formatting clean up. This ensures that the ninja
generation gets the command line invocation correct.
This patch reworks the line-directive command line argument for gyb to
take in a python-style format string with `line` and `file` variables
to be substituted.
* Generate libSyntax API
This patch removes the hand-rolled libSyntax API and replaces it with an
API that's entirely automatically generated. This means the API is
guaranteed to be internally stylistically and functionally consistent.
