The bitset(unsigned long long) constructor was broken by the constexpr additions only on 32 bit platforms.  Fixed.  This addresses http://llvm.org/bugs/show_bug.cgi?id=15444.

Added two new narrowing matchers:
* hasMethod: aplies a matcher to a CXXRecordDecl's methods until a match is made
  or there are no more methods.
* hasCanonicalType: applies a matcher to a QualType's canonicalType.

Enhanced hasOverloadedOperatorName to work on CXXMethodDecl as well as
CXXOperatorCallExpr.

Updated tests and docs.

pthread_join() returns an error code, not the result of the
pthread_create() function like I thought.

The use-null-ptr transform will transform calls to functions that return a
nullptr_t. Even if the function were to only return a null pointer and do
nothing else, this replacement would still be undesired as the behavior and
signature of the function could change in the future.

This adds an XFAILed test case to demonstrate the issue.

Adds a test for this case, which was reduced from a chromium build of

Before fix, the paren expression was being replaced resulting in returnnullptr.
ParenExpr and implicit casts now ignored so we get return(nullptr) instead.

Added new test cases.

Fixed enum printing for negative enums. There previously was no testing to validate that enum values were being displayed correctly.

Also added C++11 enum test cases to cover enums as int8_t, int16_t int32_t, int64_t, uint8_t, uint16_t, uint32_t, and uint64_t both for DWARF and dSYM cases. The DWARF being emitted by clang is missing the enum integer type, but the code is now ready to accept and deal with the integral type if it is supplied.

When considering folding a bitcast of an alloca into the alloca itself,
make sure we don't shrink the amount of memory being allocated, or
things rapidly go sideways.

Now that "settings set" will strip leading and trailing spaces, we need a way to be able to specify string values that contain spaces. So now settings setting <property> <value>" can have a <value> that is quoted:

This patch is designed for minimal intrusion into normal preprocessing
and compilation; under -E -traditional-cpp, the lexer will still
generate tok::comment nodes since it is preserving all whitespace, but
the output printer will then throw it away.

It's beneficial when compiling to treat // as the start of a line
comment even in -std=c89 mode, since it's not valid C code (with a few
rare exceptions) and is usually intended as such. We emit a pedantic
warning and then continue on as if line comments were enabled.
This has been our behavior for quite some time.

However, people use the preprocessor for things besides C source files.
In today's prompting example, the input contains (unquoted) URLs, which
contain // but should still be preserved.

This change instructs the lexer to treat // as a plain token if Clang is
in C90 mode and generating preprocessed output rather than actually compiling.
