096125deaa [es6] allow any LeftHandSideExpression in for-of loops
Fix an earlier regression which forbid non-VariableProxy LHS from being
used in for-of loops. Like for-in loops, the spec allows any LHS to be used,
with the sole exception that ObjectLiterals and ArrayLiterals must be valid
AssignmentPatterns.

Also fixes a bug in TurboFan which resulted in incorrectly replacing a variable load with a constant value in some instances, due to the AstLoopAssignmentAnalyzer failing to record the assignment to ForOfStatement's value.

4c3c89c1de Properly handle direct evals referencing super in arrow functions
The fix is to broaden the set of cases for when NeedsHomeObject()
returns true. Note that this is broader than it needs to be (since,
e.g., non-arrow function scopes inside a method can't reference
super). But we don't track the types of inner scopes at the moment,
so this is the best we can do.

be converted to a primitive with ToPrimitive and then compared again. This means,
for example, that for a Symbol or SIMD vector s, s == Object(s). This patch makes
that change in the implementation of ==. Only the runtime function needed to be
changed, as the code stubs and compiler specializations don't operate on Symbols
or SIMD vectors, and on these types, a fallback to the runtime function is always
used.

8be20eee3b Debugger: correctly report uncaught rejections in Promise.all and Promise.race.
The debugger calls PromiseHasUserDefinedRejectHandler to recursively search the
tree of dependent promises for user-defined reject handlers. If no such reject
handler exists, rejecting the promise is considered an uncaught exception.

Promise.race and Promise.all interupt the link of promise dependency wrt the
search. This change fixes that link.

e1088b27b5 [turbofan] Initial support for monomorphic/polymorphic property loads.
Native context specialization now lowers monomorphic and
polymorphic accesses to data and constant data properties on
object and/or prototype chain. We don't deal with accessors
yet, and we also completely ignore proxies (which is compatible
with what Crankshaft does).

The code is more or less the straightforward implementation. We
will need to refactor that and extract common patterns once the
remaining bits for full load/store support is in.

e2be5ce542 [parser] fix token end position for regexp literals
Make the end position of a regexp literal the first character following the regexp. This matches the behaviour of number literals and string literals, as well as single-character tokens.

This change corrects the lazy-parsing of arrow functions with concise bodies, whose last token is a regular expression literal.

24565b8598 Use Scope::function_kind_ to distinguish arrow function scopes
Previously, arrow function scopes had a separate ScopeType. However,
Scope::DeserializeScopeChain() erroneously deserialized ARROW_SCOPE
ScopeInfos as FUNCTION_SCOPE. This could lead to bugs such as the
attached one, where "super" was disallowed where it should have
been allowed.

This patch utilizes the Scope's FunctionKind to distinguish arrow
functions from others. Besides fixing the above bug, this also
simplifies code in various places that had to deal with two different
ScopeTypes both of which meant "function".
