Bug 1437004 - Porting BinAST to AST v3;r=arai,jorendorff
This patch is a nearly complete reimplementation of BinASTReader, with the following changes: - Files BinToken.h, BinSource-auto.h (new), BinSource-auto.cpp (new) are now autogenerated by the generator in js/src/frontend/binsouce from the webidl specifications of BinAST and a small configuration file. - Optional fields have been removed. Rather, some specific fields may, if so marked in the specifications, contain a Null constant. - `hasDirectEval` is now checked for consistency (NOT completeness). - `varDeclaredNames` is now checked for consistency (NOT completeness). - `lexicallyDeclaredNames` is now checked for consistency (NOT completeness). - `parameterNames` is now checked for consistency (NOT completeness). - `capturedNames` is NOT checked. - Atoms read are now properly expected to be UTF8. This patch does not implement the entire specifications, but should implement most of ES5. In particular, it is sufficient to parse the source code of: - Facebook; - jQuery; - mootools; - Underscore; - Backbone; - Angular.
