This roll includes the SharedArrayBuffer tests (skipping for now)
but doesn't include the $ renaming.
This is a reland; previously, I reverted because I was confused about why
the rename of $ to $262 didn't break tests; it now seems that the
previous patch left it as an alias. This patch does not do the renaming
yet, as the renaming usage has not landed upstream yet.

- Removes shared InnerArrayCopyWithin JS builtin from src/js/array.js
- Implements %TypedArray%.prototype.copyWithin as a C++ builtin, which
relies on std::memmove rather than accessing individual eleements.
- Fixes the case where copyWithin is invoked on a TypedArray with a
detached buffer.
- Add tests to ensure that +/-Infinity (for all 3 parameters) is handled correctly by the
algorithm
The C++ version gets through the benchmark more than 25000 times as
quickly as the JS implementation.

This patch changes the test262 infrastructure to pass individual flags,
specified in the status file, for tests for experimental features, rather
than passing --harmony for all runs. With this change, it should be
easier to run test262 tests in automation when developing new features.
The new workflow would be, when adding a flag, include the flag in the
test expectations file, and when removing the flag, remove the lines from
the test expectations file. This way, the status file does not have to
change when staging or unstaging, and you get the benefit of the automated
tests before staging starts.

This patch provides improved infrastructure for developing test262 tests
together with V8. It has three parts:
- The test262 test runner is updated to look for local versions of tests
in the /test/test262/local-tests directory, which mirrors
/test/test262/data. Additional tests can be added there and are run
together with tests from upstream. Upstream tests can be locally
updated by using the same name in local-tests; if a same-named test
exists, then only the local version will be run. The local-tests
directory is in the V8 repository, unlike the contents of the data
directory, so tests can be added in the same patch as something else.
- The tool /test/test262/upstream-local-tests.sh is added to create
a patch against the test262 respository based on a patch which changes
the local-tests directory.
- The tool /test/test262/prune-local-tests.sh is added to remove
redundant local tests on a test262 roll.

Our test infrastructure ignores missing tests which are listed in
status files. Sometimes, tests are removed and status file lines
are not updated. This patch adds a presubmit check for status
files addressing JavaScript tests to not reference missing tests.
It also cleans up existing violations.

ECMA 402 v2 made Intl constructors more strict in terms of how they would
initialize objects, refusing to initialize objects which have already
been constructed. However, when Chrome tried to ship these semantics,
we ran into web compatibility issues.
This patch tries to square the circle and implement the simpler v2 object
semantics while including a compatibility workaround to allow objects to
sort of be initialized later, storing the real underlying Intl object
in a symbol-named property.
The new semantics are described in this PR against the ECMA 402 spec:

It originates from the era where we used to run a separate preparse step
before parsing and store the function data. Now the usage of preparser
is something completely different, so this flag doesn't make sense any
more.
In addition, this way we get more test coverage for preparser (for small

GrowMemory is now implemented by changing the protection on the guard regions to

Guard pages are not enabled by default, but this change adds a flag and a test
variant to make sure we get test coverage on them.

These map checks were implemented for TF code already. This CL makes
sure that parts implemented in C++ follow the same logic, which is:
An object is an unmodified regexp if:
1) it's a receiver,
2) its map is the initial regexp map,
3) its prototype is a receiver,
4) and its prototype's map is the initial prototype's initial map.
We can now be smarter in @@replace and @@split since checking maps
(unlike the previous check of RegExp.prototype.exec) is not observable,
so we can perform fast-path checks at a time of our choosing.
