This patch brings test262 up to the latest version on GitHub. Some
highlights from new failures are:
- Reflect
- Default parameters
- Case conversion edge cases

Add a flag to explicitly filter scripts in ignition and use it for the test262
variant. The previous approach of overloading ignition-filter meant that only
top-level code was getting compiled through ignition.

This makes it explicit when the --ignition-filter pattern should be
applied to the script name instead of the function name by using a
proper "s:{name}" pattern. It also hardcodes it to be a prefix match
instead of an exact match, because that is all we need for test262.

Adds an ignition variant to the test runner and adds support to test262 for
filtering such that only test scripts (not the test harness) get run by
the interpreter.

This patch prohibits lexical bindings from being called 'let', even in
sloppy mode, following the ES2015 specification. The change affects
multiple cases of lexical bindings, including simple let/const declarations
and both kinds of for loops. var and legacy const bindings still permit
the name to be let, including in destructuring cases. Tests are added to
verify, though some cases are commented out since they led to (pre-existing)
crashes.

The current implemention breaks sloppy mode code that uses function
declarations inside blocks at top-level. Work is ongoing on a patch
to fix this issue, but in the meantime it seems reasonable to move
the feature out of staging.

Now run-tests.py understands "suite/foo/bar" with forward slashes for
command-line test selection on all test suites on all platforms.
Previously, file-based suites like mjsunit also accepted "mjsunit/foo\bar";
that behavior is sacrificed here in favor of unification. For the cctest
suite, OTOH, it wasn't possible on Windows to select specific tests at all.

This is a change for ES2015. Date objects have mutable state, so having
a mutable prototype is bad for SES requirements, and it is an
inconsistency from the typical ES2015 class style of objects

In ES5, dates were supposed to default to UTC if no timezone was specified. However, this changed in ES6, which specified that dates should be in the local timezone if no timezone was specified. This CL updates our behavior to match that part of the ES6 spec.

$toLength is slow, causing a 3.8%-8% regression in the Octane RegExp
benchmark. Reverting this patch brings it back up. To make this change,
we'll need a faster implementation fo $toLength.

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.

The final spec for Object.getPrototypeOf calls ToObject on the
parameter, which means that it should only throw for null and
undefined. For other non object values the prototype of the wrapper
should be used.
Difference from last time: Updated .status and will disable Blink

This removes the duplicate property check from object literals.
Instead we repurpose the ObjectLiteralChecker into two cases, implemented
by two subclasses to ObjectLiteralCheckerBase called ObjectLiteralChecker
and ClassLiteralChecker.
The object literal checker now only checks for duplicate __proto__ fields in
object literals.
The class literal checker checks for duplicate constructors, non constructor
fields named constructor as well as static properties named prototype.
