Modify ASTReaderListener to allow visiting the input files of an AST file.

We can pass such an input-file-visiting ASTReaderListener to ASTReader::readASTFileControlBlock.

Move PragmaCommentHandler to lib/Parse in preparation for calling Sema

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

Add missing initialization for Sema::CurScope. This is important for AST consumers which don't create a Parser. Pointed out by Tom Honermann.

Grab-bag of bit-field fixes:

  - 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.

[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.

C++ status:
 - 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

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

Have SourceManager::getLocForEndOfFile() point at the "EOF" location of the FileID.

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

Weaken an assertion in memcpyization to account for
unnamed bitfields.

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

Fix clang-format emacs integration in last line.

Emacs seems to have a line that is just past the last character of the
buffers content. This needs to be handled specially so that clang-format
is not called with an invalid -offset.

Further fix to clang-format emacs integration.

This is just a slight improvement for the fix in r181299, which fixes
formatting the very last line of a file.

Config file support for clang-format, part 1.

Summary:
Added parseConfiguration method, which reads FormatStyle from YAML
string. This supports all FormatStyle fields and an additional BasedOnStyle
field, which can be used to specify base style.
