Warn that scoped enumerations are a C++11 extenstion when compiling in
C++98 mode.  This improves on the previous diagnostic message of:

error: expected identifier or '{'

Fix formatting of complex #if expressions.

Before:
  #if !defined(AAAAAAAAAAAAAAAA) && (defined CCCCCCCC ||                         \
                                     defined DDDDDDDD) && defined(BBBBBBBB)

After:
  #if !defined(AAAAAAAAAAAAAAAA) && (defined CCCCCCCC || defined DDDDDDDD) &&    \
      defined(BBBBBBBB)

This fixes llvm.org/PR15828.

Make compares unsigned. The expression can't become negative anyways.

Silences a sign compare warning on 32 bit archs.

[analyzer] Refactor BugReport::getLocation and PathDiagnosticLocation::createEndOfPath for greater code reuse

The 2 functions were computing the same location using different logic (each one had edge case bugs that the other
one did not). Refactor them to rely on the same logic.

The location of the warning reported in text/command line output format will now match that of the plist file.

There is one change in the plist output as well. When reporting an error on a BinaryOperator, we use the location of the
operator instead of the beginning of the BinaryOperator expression. This matches our output on command line and
looks better in most cases.

[analyzer] Set the allocation site to be the uniqueing location for retain count checker leaks.

The uniqueing location is the location which is part of the hash used to determine if two reports are
the same. This is used by the CmpRuns.py script to compare two analyzer runs and determine which
warnings are new.
