Reviewed by Devin Rousso.

Command-Z used to revert all changes at once because Web Inspector never
set any history checkpoints in the style editor.

Array.prototype.flat/flatMap have a minor bug in ArraySpeciesCreate

Source/JavaScriptCore:

== null is frequently used idiom to check null or undefined in JS.
However, it has a problem in terms of the builtin JS implementation: it
returns true if masquerade-as-undefined objects (e.g. document.all) come.

In this patch, we introduce a convenient builtin intrinsic @isUndefinedOrNull,
which is equivalent to C++ JSValue::isUndefinedOrNull. It does not consider
about masquerade-as-undefined objects, so that we can use it instead of
value === null || value === @undefined. We introduce is_undefined_or_null
bytecode, IsUndefinedOrNull DFG node and its DFG and FTL backends. Since
Null and Undefined have some bit patterns, we can implement this query
very efficiently.
