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.

- 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
4658

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.

Calling quit() from d8 will call exit(), which will run static destructors. If
context_mutex_ is statically allocated, pthread_mutex_destroy will be called.

When running d8 in "isolates" mode, another thread may be running. If it calls
CreateEvaluationContext, it will lock the context_mutex_. If the mutex is
destroyed while it is locked, it will return an error.

This CL changes the Mutex to a LazyMutex, which will leak instead of being
destroyed.

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.

    the operand stack doesn't exist, hence cannot be peeked into.
