Add support for Neon VEXT (vector extract) shuffles.

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.

Fix gcc-4.4/fedora 11 by adding a sentinel value to SimpleValueType.

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.

raw_ostream: Reduce FormattedStream's reliance on raw_ostream's implementation.
...
- 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.
