Use the new cl::OptionCategory support to move the Polly options into a separate
option category. The aim is to hide most options and show by default only the
options a user needs to influence '-O3 -polly'. The available options probably
need some care, but here is the current status:

Polly Options:
Configure the polly loop optimizer

  -enable-polly-openmp              - Generate OpenMP parallel code
  -polly                            - Enable the polly optimizer (only at -O3)
  -polly-no-tiling                  - Disable tiling in the scheduler
  -polly-only-func=<function-name>  - Only run on a single function
  -polly-report                     - Print information about the activities
                                      of Polly
  -polly-vectorizer                 - Select the vectorization strategy
    =none                           -   No Vectorization
    =polly                          -   Polly internal vectorizer
    =unroll-only                    -   Only grouped unroll the vectorize
                                        candidate loops
    =bb                             -   The Basic Block vectorizer driven by
                                        Polly

clang-format become way more stable. This time we mainly reformat function
signatures.

llvm-svn: 181294

Calling 'make polly-update-format' will format all Polly files with
clang-format.

[analyzer; alternate edges] simplify optimization rules to look at control-flow conditions to prune edges.

unnamed bitfields.

Unnamed bitfields won't have an explicit copy operation
in the AST, which breaks the strong form of the invariant.

We were passing an i32 to ConstantInt::get where an i64 was needed and we must
also pass the sign if we pass negatives numbers. The start index passed to
getConsecutiveVector must also be signed.

Should fix PR15882.

This fixes a crash due to SourceManager::getLocForEndOfFile() returning an off-by-one location
when the the FileID is for an empty file.

C++1y: an assignment operator is implicitly 'constexpr' if it would only call 'constexpr' assignment operators for a literal class type.

 - fix paper links to point to isocpp.org, where most of the papers are already up
 - update "SVN" features to "Clang 3.3" to distinguish them from features which we
   complete after the branch
 - document use of -std=c++1y to enable c++1y support

This makes the target handler a constructor argument because the constructor of
OutputELFWriter relies on it being initialized.

If the user pressed ^D, that would bypass the exit confirmation mechanism
This checkin remedies that by making sure that users get prompted on exit when appropriate even if they use CTRL+D instead of typing quit at the prompt

[analyzer; alternate arrows] don't increment the path iterator when we just deleted the next iterator.

This is an optimization.  It is possible that by deleting the next
edge we will pattern match again at the current spot.

  - References to ObjC bit-field ivars are bit-field lvalues;
    fixes rdar://13794269, which got me started down this.
  - Introduce Expr::refersToBitField, switch a couple users to
    it where semantically important, and comment the difference
    between this and the existing API.
  - Discourage Expr::getBitField by making it a bit longer and
    less general-sounding.
  - Lock down on const_casts of bit-field gl-values until we
    hear back from the committee as to whether they're allowed.

Summary:
No functionality change.  The existing tests for this pragma only verify
that we can preprocess it.
