Support for Mips register information sections.
Mips ELF object files have a section that is dedicated
to register use info. Some of this information such as
the assumed Global Pointer value is used by the linker
in relocation resolution.
The register info file is .reginfo in o32 and .MIPS.options
in 64 and n32 abi files.
This patch contains the changes needed to create the sections,
but leaves the actual register accounting for a future patch.

Some instructions like memory reads/writes are executed
asynchronously, so we need to insert S_WAITCNT instructions
to block before accessing their results. Previously we have
just inserted S_WAITCNT instructions after each async
instruction, this patch fixes this and adds a prober
insertion pass.

We shouldn't insert KILL optimization if we don't have a
kill instruction at all.

Because the Attribute class is going to stop representing a collection of
attributes, limit the use of it as an aggregate in favor of using AttributeSet.
This replaces some of the uses for querying the function attributes.

grep is now only mentioned once in a sentence that explicitly says it's
deprecated. For FileCheck, there's no reason to repeat part of the
documentation that exists in CommandGuide/FileCheck.

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.

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.

_Complex float and _Complex long double, by simply increasing the
number of floating point registers available for return values.
The test case verifies that the correct registers are loaded.
