This reverts commit r189886.
I found a corner case where this optimization is not valid:
Say we have a "linkonce_odr unnamed_addr" in two translation units:
* In TU 1 this optimization kicks in and makes it hidden.
* In TU 2 it gets const merged with a constant that is *not* unnamed_addr,
resulting in a non unnamed_addr constant with default visibility.
* The static linker rules for combining visibility them produce a hidden
symbol, which is incorrect from the point of view of the non unnamed_addr
constant.
The one place we can do this is when we know that the symbol is not used from
another TU in the same shared object, i.e., during LTO. I will move it there.

The reason that I am turning off this optimization is that there is an
additional case where a block can escape that has come up. Specifically, this
occurs when a block is used in a scope outside of its current scope.
This can cause a captured retainable object pointer whose life is preserved by
the objc_retainBlock to be deallocated before the block is invoked.
An example of the code needed to trigger the bug is:
----
\#import <Foundation/Foundation.h>

NSObject *obj = [NSObject new];

Nuke the hilariously out of date suggestion to unpack llvm-gcc 4.2 as
part of getting started with LLVM.
The LLVM getting started document is in woeful need of attention. I may
get to some of this, but some random notes for folks interested:
1) We need to separate the getting started steps for folks who are
interested in the core LLVM libs and nothing else, folks interested
in a nifty C++ toolchain and nothing else, and folks interested in
both.
2) We should include documentation for both release archives, svn, and
git in equal portion, and we should document all of the various
repositories of interest: llvm, clang, clang-tools-extra,
compiler-rt, lld, libcxx, test-suite.
3) We should document the CMake build. We should probably document the
CMake build first, and give a fall-back set of docs for the Makefile
build for the use cases where that is still the preferred solution.
This would more closely match the use cases that folks in the open
source community are likely to have, and would remove a point of
discrepancy between Linux, Windows, and Mac instructions.
4) Probably a ton of other modernization stuff that I've not thought of
here.

in to TargetSelectInstruction(), and when I did I realized it wasn't
serving any useful purpose. This is only useful for compares that
don't feed a branch in the same block, and to handle that we would
have to have logic to interpret i1 as a condition register. This
could probably be done, but would require Unseemly Hackery, and
honestly does not seem worth the hassle.
This ends the current patch series.

[PowerPC] Add integer truncation support to fast-isel.
This is the last substantive patch I'm planning for fast-isel in the
near future, adding fast selection of integer truncates. There are
certainly more things that can be improved (many of which are called
out in FIXMEs), but for now we are catching most of the important
cases.
I'll document some of the remaining work in a cleanup patch shortly.

Remove the suggestion to not duplicate comments in header and
implementation files. While doc generation systems don't need this,
humans do benefit from it. Not everyone reads all code through doxygen.

[PowerPC] Call support for fast-isel.
This patch adds fast-isel support for calls (but not intrinsic calls
or varargs calls). It also removes a badly-formed assert. There are
some new tests just for calls, and also for folding loads into
arguments on calls to avoid extra extends.
