 - 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.

Add a hack to unbreak MSVC builds. str(n)casecmp are POSIX functions and aren't available on windows (mingw defines them though).

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.

 - Kill off begin(), end(), and iterator. It isn't clear what these
   mean. Instead provide getBufferStart(), which can be used with
   GetNumBytesInBuffer to the same effect.

 - Update ComputeColumn to take arguments for the buffer to scan, this
   simplifies the implementation of write_impl substantially.

 - This should also fix possible problems with the scanning pointer pointing
   outside of the current raw_ostream buffer.
