This CL implements MemoryAllocator::LookupChunkContainingAddress, which

V8 compaction, which currently runs before verification, can update
stack slots, which could lead to more false positives when we scan
compressed pointers on stack. The CL disables the stack verification if
pointer compression. The intent is to investigate if verification can be

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.
