This further reduces the number of things declared in the public regexp API file, currently still named jsregexp.h. * Move JSRegExp::Flags convenience functions to regexp-compiler.h. * Set RegExpImpl methods private if possible (these will later be moved to a new hidden impl class). * Merge RegExpEngine::CompilationResult into RegExpCompileData. * Move remaining RegExpEngine methods to RegExpImpl and delete RegExpEngine. * Extract RegExpGlobalCache. * Document a few data structures. Upcoming CLs will rename RegExpImpl to RegExp and jsregexp.h to regexp.h. This should then be the only header included from other directories.

Andreas Haas authored
In the existing code, whenever unreachable control instructions needed values from the stack which were not available, values of type kWasmVar were put on the stack. When these values were type-checked the first time, the expected type was assigned to them for later validation. This behavior has several draw-backs: * In an unobservable way, this implementation does not match the requirements of the spec. With the anyref proposal, this difference becomes observable. * Type checking functions were not read-only anymore, because if unreachable code was validated, the stack got manipulated in these functions. With the refactoring, I pulled out the handling of unreachable code out of the type checking functions. These checking functions can be validation-only functions. For type checking unreachable code, I start by popping values of the expected types off the stack. Thereby all available values on the stack get type-checked. Afterwards, I push all values again on the stack with the expected type if needed. This allows to continue the expected type checking for later instructions.

RegExp assertions (e.g.: '^', '$', '\b', ...) sequences have certain properties that this rewriter exploits: 1. They are zero-width and order-independent, thus one can remove all duplicate assertions. 2. If a subsequence is guaranteed to fail, the entire sequence fails. Any sequence always known to fail (e.g. containing both '\b' and '\B') can be rewritten to a single node that triggers failure. This CL generalizes the previous optimization for repeated assertions to be order-independent, i.e. assertions only have to be in the same sequence but not next to each other.
