Original commit message:
[turbofan] Boost performance of Array.prototype.shift by 4x.
For small arrays, it's way faster to just move the elements instead of
doing the fairly complex and heavy-weight left-trimming. Crankshaft has
had this optimization for small arrays already; this CL more or less
ports this functionality to TurboFan, which yields a 4x speed-up when
using shift on small arrays (with up to 16 elements).
This should recover some of the regressions reported in the Node.js issues
https://github.com/nodejs/node/issues/12657
and discovered for the syncthrough module using
https://github.com/mcollina/syncthrough/blob/master/benchmarks/basic.js

Alternative approach to https://codereview.chromium.org/2667983004/, which
does not depend on implicit control flow changes from
https://codereview.chromium.org/2664083002
- Remove handling for `async function` from Parser::RewriteReturn(). This functionality
is moved to BytecodeGenerator::BuildAsyncReturn(). This ensures that promise resolution
is deferred until all finally blocks are evaluated fully.
- Add a new deferred command (CMD_ASYNC_RETURN), which instructs ControlScope to
generate return code using BuildAsyncReturn rather than BuildReturn.
- Parser has a new `NewReturnStatement()` helper which determines what type of return
statement to generate based on the type of function.

Original commit message:
ValueSerializer: Promote scheduled exceptions from wasm::ErrorThrower.
wasm::ErrorThrower doesn't actually throw exceptions, it just schedules them.
As a result, this exception isn't handled properly by code which expects
ValueDeserializer to actually throw. For instance, the unit tests use a
TryCatch to catch and handle expected exceptions in unit tests.
Before this patch, I see local unit test failures because a wasm decode test
schedules one, but it isn't caught (and instead causes Context::New to fail
at the beginning of the next test).

Original commit message:
ValueSerializer: Support efficiently reading and writing one-byte strings.
memcpy is faster than UTF-8 encoding/decoding. This yields 10-20% wins on
serializing and deserializing long ASCII strings, according to
blink_perf.bindings -- and these are already in a fast path where the entire
string is known to be ASCII (but this has to be checked). The win may be
larger for strings in Latin-1 but not ASCII (though I suspect this is an
uncommon case).
A change is also made to make ValueSerializerTest.EncodeTwoByteStringUsesPadding
survive wire format version number changes.
This is the first of a series of wire format changes from the previous Blink
format. The deserializer continues to be able to read the old format, but
Chromium M56 will no longer be able to read the messages written by this, in M58.

Original commit message:
ValueSerializer: Distinguish between 'undefined' and an absent property.
Dealing with this case requires a wire format change. It is possible that an
element can be absent even in an array where the dense format was chosen
(because the array initially had no holes), if the elements are modified while
they are being serialized. In this case, a new tag for the "hole" is emitted.
The logic to treat undefined in dense arrays as an absent property is restricted
to versions of the wire format that this tag did not exist.

Original commit message:
ValueDeserializer: Only allow valid keys when deserializing object properties.
The serializer won't ever write a more complex object. Not validating this
allows other things to be used as keys, and converted to string when the
property set actually occurs. It turns out this gives an opportunity to trigger
OOM by giving an object a key which is a very large sparse array (whose string
representation is very large).
This case is now rejected by the deserializer.

Original commit message:
ValueDeserializer: Make sure that an exception is the legacy path.
The entry points to the deserializer are responsible for ensuring that an
exception is pending by the time they return. Some failures throw exceptions
themselves, while others (like errors in the format) are exceptions caused by
the deserializer, not coming from the runtime.
Like the non-legacy path, a default deserialization exception should be thrown
in such cases.

switch block pushes a block context: the current context is
a block context, but the scope analysis based on the current
source position tells the debugger that we should be outside

Orignial commit message:
[crankshaft] No need to rely on the @@hasInstance protector.
In Crankshaft we can actually do an abstract interpretation of the
@@hasInstance lookup when optimizing instanceof and then use the
normal machinery to protect the result instead of relying on the
global @@hasInstance protector cell for optimizations.
This recovers the 100x performance drop in Node.js v7 reported in
https://github.com/nodejs/node/issues/9634. This patch should be
easily back-mergable to Node.js v7.
