https://github.com/tc39/ecma262/pull/988 gained concensus during the september 2017 TC39 meetings. This moves the load of the "next" method to the very beginning of the iteration protocol, rather than during each iteration step. This impacts: - yield* - for-of loops - spread arguments - array spreads In the v8 implementation, this also affects async iteration versions of these things (the sole exception being the Async-From-Sync iterator, which requires a few more changes to work with this, likely done in a followup patch). This change introduces a new AST node, ResolvedProperty, which can be used as a callee by Call nodes to produce the same bytecode as Property calls, without observably re-loading the property. This is used in several AST-desugarings involving the iteration protocol.

The timezone offset in effect on Dec 25, 1995 won't be applicable in years far away from 1995 (e.g. year 1111). Calculate the timezone offset in Feb 1, 1995 and run other tests on the same day. This issue has been hidden because the current implementation doesn't take into account the history of timezone offset changes(crbug.com/3547), but was exposed when a correct implementation based on ICU was tried.

Band-aid fix for infinite recursion in RegExp TFJ builtins. TFJ builtins don't contain stack checks in general, so any deep recursion involving only TFJ builtins can end up overflowing the stack and segfaulting on the red area. RegExp builtins in particular can only build such recursions using RegExp.p.exec, and (as far as I can tell) only by modifying the instance or prototype, thus hitting the slow path in all builtins. This CL adds a stack check to RegExpExec, which is the choke point for calling exec on slow-mode RegExps.
