The spec got rid of `CheckObjectCoercible` a while back, and so should
we. This change is not observable in most of the affected cases since
`ToObject` is up near the top of most Array method algorithms. An
example of an observable effect of this change occurs for the following
input:
Array.prototype.sort.call(null, 1);
Behavior before applying the patch (incorrect message):
TypeError: Array.prototype.sort called on null or undefined
Expected behavior:
TypeError: The comparison function must be either a function or
undefined
This patch removes `CheckObjectCoercible` and adds tests to ensure the
few observable cases are addressed correctly.
The patch also adds a missing `ToObject(this)` to
`Array.prototype.lastIndexOf` which would otherwise become observable
as a result of `CheckObjectCoercible` being removed.

Our testing infrastructure uses exceptions to indicate
errors. assertUnreachable therefore throws an exception to indicate
that it was reached. Therefore, it cannot be used to check that an
exception was thrown using the pattern:
try {
shouldThrow();
assertUnreachable();
} catch(e) {
}
Such a test will always pass because assertUnreachable will throw an
exception if shouldThrow does not.

The only difference to revision 7763 is the implementation in the
builtins file for arm and x64, plus a move of Array.prototype.toString
and Array.prototype.toLocaleString from should throw on null or
undefined to the non generic test cases in the function-call test (due
to us not currently supporting generic cases with these to functions)
