Mike Stanton fd334b3216 [builtins] Enable Torque Array.prototype.splice
Before, splice was implemented with a C++ fast path and a
comprehensive JavaScript version.

This impl. is entirely in Torque with a fastpath for SMI,
DOUBLE and OBJECT arrays, and a comprehensive slow path.
The same level of "sparse" array support as given by the
array.js implementation is included.

This reland addresses several issues:

* Removed "sparse" array support from splice.
* Addressed ClusterFuzz issue 876443:
  The test and code that uses the fix is in this CL.
  The fix in isolation can be seen here:
  https://chromium-review.googlesource.com/c/v8/v8/+/1199403
* Removed dead code in elements.cc

This directory contains code for binding the test262 test suite
into the v8 test harness. The tests are checked out as a dependency from

  https://chromium.googlesource.com/external/github.com/tc39/test262

at a revision specified in the DEPS file as 'data' in this directory. They are
fetched with 'gclient sync'. To update to a newer version, please change the
DEPS file.

Using a newer version, e.g. 'deadbeef' may be possible but the tests are only
known to pass (and indeed run) with the DEPS revision. Example:

  cd data
  git fetch
  git checkout deadbeef

If you do update to a newer revision you may have to change the test
harness adapter code since it uses internal functionality from the
harness that comes bundled with the tests.  You will most likely also
have to update the test expectation file.
