This CL improves the performance of creating [...a, b] or [...a].
If the array literal has a leading spread, this CL emits the bytecode
[CreateArrayFromIterable] to create the literal. CreateArrayFromIterable
is implemented by [IterableToListDefault] builtin to create the initial
array for the leading spread. IterableToListDefault has a fast path to
clone efficiently if the spread is an actual array.
The bytecode generated is now shorter. Bytecode generation is refactored
into to BuildCreateArrayLiteral, which allows VisitCallSuper to benefit
from this optimization also.
For now, turbofan also lowers the bytecode to the builtin.
The idiomatic use of [...a] to clone the array a now performs better
than a simple for-loop, but still does not match the performance of slice.

Previously the logic was implemented for mjsunit, now it will be used
across all d8-based test cases.
This'll enable adding those test suites for Android testing.

For memory tracing, output a 'T' for Turbofan code and an 'L' for
Liftoff code. To do this, the WasmCodeWrapper now has some dispatch
functions which work for both on-the-heap and off-the-heap code.
We can probably refactor more code by having this mechanism.
Since the output of --wasm-trace-memory differs now between Turbofan
and Liftoff, the message test is split in two.

This adds support for tracing memory operations in code compiled with
Liftoff. This is the first runtime call we emit from Liftoff code, so
part of this code can be reused for other runtime calls.
Drive-by: Reuse outer compilation zone (avoid one Zone allocation).

Instead of passing four arguments to the runtime function, just pass
one pointer to a struct containing all information. This makes it much
easier to implement memory tracing in Liftoff in a follow-up CL.
Also fix a few other minor things like the namespace and the include
guards.

The spec got rid of `CheckObjectCoercible` a while back, and so should
we. This change is not observable in most of the affected cases since
`ToObject` is up near the top of most Array method algorithms. An
example of an observable effect of this change occurs for the following
input:
Array.prototype.sort.call(null, 1);
Behavior before applying the patch (incorrect message):
TypeError: Array.prototype.sort called on null or undefined
Expected behavior:
TypeError: The comparison function must be either a function or
undefined
This patch removes `CheckObjectCoercible` and adds tests to ensure the
few observable cases are addressed correctly.
The patch also adds a missing `ToObject(this)` to
`Array.prototype.lastIndexOf` which would otherwise become observable
as a result of `CheckObjectCoercible` being removed.

Currently, Declaration stores a Scope pointer to whichever Scope the
declaration appeared in. This is used to disallow var declarations
being hoisted over lexical declarations. For example:
{
let x;
{ var x; }
}
But in fact this is the only sort of case where storing the scope
is required: for lexical declarations (including function declarations
appearing in blocks), Declaration::scope() was always identical to
Declaration::proxy()->var()->scope(). That is, only var declarations
end up "nested" in this way.
This patch adds a subclass of VariableDeclaration to store the Scope.
Since the only thing that cares about that data is Scope analysis,
this isn't treated as a distinct AstNode::NodeType from VariableDeclaration,
leaving all AstVisitors untouched in the process.
Also reworked the logic in Scope::CheckConflictingVarDeclarations() for
clarity after making changes to accomodate the new code.

The patch changes CallPrinter's AST traversal to continue even after
the first positive match for an AST node. This helps us check for the
subsequent GetIterator AST node in case of destructuring.
We can not differentiate between the function call failing and the
GetIterator failing based on source position info. This would involve
runtime checks costing performance.
Instead of providing an incorrect error, we provide both the
possiblities to user and allow them to disambiguate.

Previously, when destructuring against null or undefined we would
print:
d8> var { x } = null
(d8):1: TypeError: Cannot match against 'undefined' or 'null'.
var { x } = null
^
TypeError: Cannot match against 'undefined' or 'null'.
at (d8):1:1
The above message uses the term "match" which isn't a common term in
JavaScript to describe destructuring. This message also doesn't
provide the name of the property that fails destructuring.
This patch changes the error message to be:
d8> var { x } = null;
(d8):1: TypeError: Cannot destructure property `x` of 'undefined' or 'null'.
var { x } = null;
^
TypeError: Cannot destructure property `x` of 'undefined' or 'null'.
at (d8):1:1
This patch changes the message to say "destructure" instead of "match".
This patch adds support for printing property names that are string
literals. We iterate through every property and pick the first string
literal property name if it exists. This provides at least some
feedback to the developer.
This patch also makes the pointer point to the position of the
property name that fails destructuring.
For computed and numeric property names, we print a generic error:
d8> var { 1: x } = null
(d8):1: TypeError: Cannot destructure against 'undefined' or 'null'.
var { 1: x } = null

Separate the function that prints type profile with
--type-profile from the one that collects type profile.
The name needs to be stored in the feedback vector as well. I'll make a
follow up CL that stores the relevant information, so it can
be printed later.

Collect type information for JavaScript variables and display it
in Chrome DevTools.

When debugging JavaScript, it’s helpful to know the type of
a variable, parameter, and return values. JavaScript is
dynamically typed, and for complex
source code it’s often hard to infer types. With type profiling, we
can provide type information to JavaScript developers.
This CL is a proof of concept. It collects type profile for
assignments and simply prints the types to stdout.
The output looks something like this:
#my_var1
#Object
#number
#string
#number
#undefined
#string
#Object
#Object
We use an extra slot in the feedback vector of assignments to
carry the list of types for that assignment. The extra slot is
only added when the flag --type-profile is given.
Missing work:
* Collect data for parameters and return values (currently only assignments).
* Remove duplicates from the list of collected types and use a common base class.
* Add line numbers or source position instead of the variable name.
For now, has a test that compares the stdout of --type-profile in test/message. We
will remove this test when --type-profile is fully integrated in
the debugger protocol. Adding
the test in test/inspector does not work, because the inspector
test itself consists of JavaScript code that would convolute the
output and be non-deterministic under stress.

The order in which things were done wasn't quite correct and lead
to wrong behaviour for certain circular module graphs.

https://codereview.chromium.org/2694003002/ introduced
"SyntaxError: Lexical declaration cannot appear in a single-statement context"
for the case when let + desctructuring from a list happen.
As was pointed out in https://codereview.chromium.org/2694003002/#msg18, the
case without destructuring would also benefit from a better message: if a
single statement is expected and "let identifier = ..." is seen, the error is
indeed again that the lexical declaration is not a statement. However, the current
error is "Unexpected identifier", because the parser tries to accept "let" as
an identifier in an expression statement, and then gives up seeing the other
identifier after "let".
This CL ensures that the parser recognises the error properly and reports
accordingly. It also renames the existing test, which contains destructuring,
and adds the one with a non-destructuring lexical declaration.

ES2017 forbids the sequence of tokens "let [" in in expression statements [1].
This CL makes ParserBase report those instances as SyntaxError. It also adds a
customised error message for that, because the standard "Unexpected token" is
not applicable: "let" itself is not forbidden in those context, only the
sequence of "let [".

Also updated some tests due to the change. The general pattern is when a
trailing comma is expected to cause a SyntaxError, an additional comma was
added.

The current logic in Isolate::GetLocationFromStackTrace just ignores
wasm frames, making the computed location point to the first javascript
frame, like this:
test.js:17: RuntimeError: divide by zero
module.exports.main();
^
RuntimeError: divide by zero
at main (<WASM>[1]+5)
at test.js:17:16
This CL not only fixes the location to point to the top-most wasm
frame, but also exposes to the embedder that the script of that location
is a wasm script, allowing for custom printing of wasm locations.
The Shell::ReportException method now checks for this flag, and prints
wasm locations like this:
<WASM>[0]+5: RuntimeError: divide by zero
RuntimeError: divide by zero
at main (<WASM>[0]+5)
at test/message/wasm-trap.js:15:16
