 - This avoids unnecessary malloc/free overhead in the common case, and
   unnecessary copying from the ostream buffer into the output vector.

 - These allow clients to make use of the extra elements in the vector which
   have already been allocated, without requiring them to be value initialized.

This is derived from a patch by Anton Korzh.  I modified it to recognize
the VEXT shuffles during legalization and lower them to a target-specific
DAG node.

gcc-4.4 was optimizing away comparisons against SimpleValueType when
it was compared to a value larger than the largest value in the enum.
This patch works around it by adding one extra item to the enum so
that these tests will now be valid.
