    [regexp] SpiderMonkey embedding fixes · 6beb0cf4
    Iain Ireland authored
    There are two changes in this patch.
    
    1. We previously added `VerifyRegExpSyntax` in regexp-parser.h to support checking regexp syntax for early errors in SpiderMonkey. Now that V8 is also emitting early errors for regexps (bug v8:896), SpiderMonkey can use the same code as V8.
    
    2. Bug v8:11069 used a std::unordered_map as a cache for range arrays. This is currently the only place in irregexp that can call non-placement new, which SpiderMonkey has a static analysis to detect. Converting this to a ZoneUnorderedMap solves the problem for us, and seems consistent with the rest of irregexp.
    
    Bug: v8:13108
