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

   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.

Anyways, if anyone at all is interested, please help clean up this
document. It is much needed.

Revert: r189565 - Add getUnrollingPreferences to TTI

Revert unintentional commit (of an unreviewed change).

Original commit message:

Add getUnrollingPreferences to TTI

Allow targets to customize the default behavior of the generic loop unrolling
transformation. This will be used by the PowerPC backend when targeting the A2
core (which is in-order with a deep pipeline), and using more aggressive
defaults is important.

Add useAA() to TargetSubtargetInfo

There are several optional (off-by-default) features in CodeGen that can make
use of alias analysis. These features are important for generating code for
some kinds of cores (for example the (in-order) PPC A2 core). This adds a
useAA() function to TargetSubtargetInfo to allow these features to be enabled
by default on a per-subtarget basis.

Here is the first use of this function: To control the default of the
-enable-aa-sched-mi feature.
