fae9057bf0 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.

rather obscure way (the other candidate is r79377).

935d99e9df 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.

69a97af0b7 Privatize part of the leak detector mechanism, which turned out to be heavily contended
when trying to run opt in parallel.  This lets parallel opt crunch 403.gcc in about a third

85b15d8e71 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.

9496240bbf Simplify RegScavenger::FindUnusedReg.
- Drop the Candidates argument and fix all callers. Now that RegScavenger
  tracks available registers accurately, there is no need to restict the
  search.
- Make sure that no aliases of the found register are in use. This was a potential bug.

1d84247c99 Fix a bug in raw_ostream::write(char) introduced by the change to
allow underlying stream classes to decline buffering. After
calling SetBuffered(), re-check whether the stream is Unbuffered
in order to handle the case where the underlying stream has
declined buffering.
