317794939c Streamline the mentions of grep and FileCheck in TestingGuide.rst 
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.

167ede898a Reverting r171325 & r172363. This was causing a mis-compile on the self-hosted LTO build bots. 
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.

02c6325a45 Provide a place for targets to insert ILP optimization passes. 
Move the early if-conversion pass into this group.

ILP optimizations usually need to find the right balance between
register pressure and ILP using the MachineTraceMetrics analysis to
identify critical paths and estimate other costs. Such passes should run
together so they can share dominator tree and loop info analyses.

Besides if-conversion, future passes to run here here could include
expression height reduction and ARM's MLxExpansion pass.

c147b67820 This is a resubmittal. For some reason it broke the bots yesterday

tested for assembler or dissassembler consumption. This patch
adds that functionality.
