Summary:
This allows unit tests for components that use Support/Debug.h to print
debug information from test runs by specifying -debug when running the
test.

Calculate vector element size more directly for VINSERTF128/VEXTRACTF128 immediate handling. Also use MVT since this only called on legal types during pattern matching.

Check for less than 0 in shuffle mask instead of -1. It's more consistent with other code related to shuffles and easier to implement in compiled code.

Okay, here's how to reproduce the problem:

1) Build a Release (or Release+Asserts) version of clang in the normal way.

2) Using the clang & clang++ binaries from (1), build a Release (or
   Release+Asserts) version of the same sources, but this time enable LTO ---
   specify the `-flto' flag on the command line.

3) Run the ARC migrator tests:

    $ arcmt-test --args -triple x86_64-apple-darwin10 -fsyntax-only -x objective-c++ ./src/tools/clang/test/ARCMT/cxx-rewrite.mm

You'll see that the output isn't correct (the whitespace is off).

The mis-compile is in the function `RewriteBuffer::RemoveText' in the
clang/lib/Rewrite/Core/Rewriter.cpp file. When that function and RewriteRope.cpp
are compiled with LTO and the `arcmt-test' executable is regenerated, you'll see
the error. When those files are not LTO'ed, then the output of the `arcmt-test'
is fine.

It is *really* hard to get a testcase out of this. I'll file a PR with what I
have currently.

 - This code is dead, and the "right" way to get this support is to use the
   platform-specific linker-integrated LTO mechanisms, or the forthcoming LLVM
   linker.
