Previously the message was "this is not defined" which is nonsensical.

Change bytecode-expectations-printer.cc in the cctest application so
that intrinsic function names are printed rather than their native
context index.
This minimizes the amount of unnecessary changes to the bytecode
expectations that need to happen whenever the context fields are
changed.

Previously, the Intl.DateTimeFormat constructor and other related paths had
a bug where the options bag passed in would be modified in place. This patch
makes V8's Intl implementation follow the specification's logic to avoid
such a modification.

This is so that a NotSuperConstructor error is thrown before evaluating the
arguments to the super constructor. Besides updating the runtime function, a
new bytecode GetSuperConstructor is introduced.

This introduces an explicit struct for the communication channel between
the {ArrayLiteral} AST node and the corresponding runtime methods. Those
methods take a pair of {ElementsKind} as well as an array (can either be
a FixedArray or a FixedDoubleArray) of constant values.
For bonus points it also reduces the size of the involved heap object by
one word (i.e. length field of FixedArray not needed anymore).

Allocate the registers used as arguments to a call on-demand after visiting the
argument (or reciever). This means that the visited expression can use registers
that would otherwise have been allocated for arguments which haven't been
visited yet.
The reason for doing this is to avoid keeping things live in registers
unecessarily for chained function calls, which avoids a memory leak for
functions which chain a large number of calls with large temporary arguments /
recievers.

The evaluation order of this argument was accidentally changed when the
special-case was added for super calls with a final spread argument.

The patch was reverted due to a bug - we failed to evict OSR-optimized
code in the case where the SharedFunctionInfo OptimizedCodeMap was
empty/cleared.
Since we OSR code rarely, it makes sense to store it and look for it on the native context rather than the SharedFunctionInfo. This makes the OptimizedCodeMap data structure more space efficient, as it doesn't have to store an ast ID for the OSR entry point.

-- Moves promiseHasHandlerSymbol to inobject property
-- Ports PromiseResolveClosure to TF
-- Fix a non spec async-await test which fails now because we do a map
check for native promise check (instead of IsPromise). Changing the
constructor (in the test) invalidates the map check.
This patch results in a 7.1% performance improvement in the bluebird
benchmark (over 5 runs).

This allows to detect a static property also named 'name', and also makes sure 'name' is added last, to be standards-compliant.

This just calls into a runtime function for implementation currently.
Intermediate step in speeding up constructor calls containing a spread.
The NewWithSpread bytecode will probably end up having different arguments with future CLs - the constructor and the new.target should have their own regs. For now we are calling into the runtime function, so we need the regs together.

Unfortunately we have to split this up into two cases: those with exactly one spread argument as the final argument, and all others, due to any side-effects of evaluation being visible.
This is in preparation for a new bytecode which handles super calls.
