Test patch, index

According to the Selection spec for extend [1], the checking of offset compared
to parentNode's length should be done before setting the new boundary points
for the range [2] which would trigger the node type exception for doctype.

In the selecttest/extend.html tests there are a few tests that expect the
browser to throw an INVALID_NODE_TYPE_ERR, where in fact the INDEX_SIZE_ERR
exception should be checked and thrown first.

Patch attached.
