NumberFormat previously just used a min of 0 digits after the decimal and a max of 3. This CL changes it so that we use the ICU currency data, and set the min and max to the number of numbers after the decimal point for each currency.
This CL also fixes a small bug where if the minimum fraction digits is above 3 but the maximum fraction digits isn't set, then it returns with only three numbers after the decimal point.

Additionally, push the allocation site or undefined independently of creating a memento to preserve a fixed size for the construct frames.

- Test that TypedArray properties cannot be set in strict mode
Properties like %TypedArray%.prototype.length have a getter and no
setter. This test verifies that property, which was apparently not
true in the past or had no test ensuring throwing in this case.
- Test that TypedArray integer indexed properties (array elements)
are not configurable
Both of these have passed for some time, but there are open bugs against
them and apparently no tests verifying that they are fixed.

This is a change from ES5 to ES6: When reversing an array, first it is checked
whether the element exists, before the element is looked up. The order in ES6
is
[[HasElement]] lower
[[Get]] lower (if present)
[[HasElement]] upper
[[Get]] upper (if present)
In ES5, on the other hand, the order was
[[Get]] lower
[[Get]] upper
[[HasElement]] lower
[[HasElement]] upper
To mitigate the performance impact, this patch implements a new, third copy
of reversing arrays if %_HasPackedElements. This allows us to skip all
membership tests, and a quick and dirty benchmark shows that the new version
is faster:
Over 4 runs, the slowest for the new version:
d8> var start = Date.now(); for (var i = 0; i < 100000000; i++) [1, 2, 3, 4, 5].reverse(); Date.now() - start

Over 3 runs, the fastest for the old version:
d8> var start = Date.now(); for (var i = 0; i < 100000000; i++) [1, 2, 3, 4, 5].reverse(); Date.now() - start

ES2015 made a change vs ES5, where the "lastIndex" property of a
RegExp (which can be modified by a user to start the next search at
a different location) is cast to an integer with ToLength rather
than ToInteger. The main difference is on negative numbers, and
this is tested by test262. This patch implements that change on
RegExps and enables the test262 test now that it passes.

This CL exposes the constructor function, defines type related
information, and implements value type semantics.
It also refactors test/mjsunit/samevalue.js to test SameValue and SameValueZero.

This makes the implicit initializing assignment to 'this' performed
after a super constructor call explicit in the AST. It removes the
need to handle the special case where a CallExpression behaves like a
AssignmentExpression from various AstVisitor implementations.

These were added when I thought they would be useful in Blink, but as
it turned out they were not. They could likely be deleted immediately,
but to play it safe I'll go through the usual deprecation process.

During parsing, we now keep track of the first spread seen in an array
literal (if any), and make use of that information when creating the
FixedArray backing store representing the constant elements for array
literal materialization.
The old code tried to do this by setting the generated JSArray's length
in ArrayLiteral::BuildConstantElements(), but that Array length is never
read by the rest of the literal materialization code (it always uses
the length of the FixedArray backing store).

By not having to patch the return sequence (we patch the debug
break slot right before it), we don't overwrite it and therefore
don't have to keep the original copy of the code around.

A sloppy mode eval call that establishes strict mode will leak that strictness
into the sloppy surrounding scope on recompile. This changes the structure
of the type feedback vector for the function and crashes follow.
The fix is straightforward.
