Jakub Staszak spotted this in review. I don't notice these things
until I manually rerun benchmarks. But reducing unit tests is a very
high priority.

We do this by using the "most recent" good location: if a synthesized
function 'A' calls another function 'B', the path notes for the call to 'B'
will be placed at the same location as the path note for calling 'A'.
Similarly, the call to 'A' will have a note saying "Entered call from...",
and now we just don't emit that (since the user doesn't have a body to look
at anyway).
Previously, we were doing this for the "Calling..." notes, but not for the
"Entered call from..." or "Returning to caller". This caused a crash when
the path entered and then exiting a call within a synthesized body.

expressions that refer to ivars will not work because Clang
emits IR that refers to them to get the ivar offsets.
However, it is possible to search the runtime for these values.
I have added support for reading the relevant tables to the
Objective-C runtime, and extended ClangExpressionDeclMap to
query that information if and only if it doesn't find the symbols
in the binary.
Also added a testcase.

not ReadExpr().
Also add a test case making sure the thread safety attributes work as expected
when they come from a PCH.
Fixes rdar://12584141 & http://llvm.org/PR13982

type-name is looked up in the context of the complete postfix-expression. Don't
forget to pass the scope into this lookup when the type-name is a template-id;
it might name an alias template which can't be found within the class itself.
Bug spotted by Johannes Schaub on #llvm.

BinaryOperator::Opcode. This is bad form, and the behavior of the static_cast
in this case is unspecified according to the standard.
Fixes a warning that showed up from r167992 on self-host.

working with preprocessed testcases. This causes source locations in
diagnostics to point at the spelling location instead of the presumed location,
while still keeping the semantic effects of the line directives (entering and
leaving system-header mode, primarily).

PPC64 target. The five tests modified herein test code generation that is
sensitive to the code model selected. So I've added -code-model=small to
the RUN commands for each.
Since small code model is the default, this has no effect for now; but this
prepares us for eventually changing the default to medium code model for PPC64.
Test changes verified with small and medium code model as default on
powerpc64-unknown-linux-gnu. All tests continue to pass.

type conversion between integers. This allows the warning to be more accurate.
Also, turned the warning off in an analyzer test. The relavent test cases
are covered by the tests in Sema.

type as written from the ParmVarDecl; it's unclear whether the standard
(C99 6.9.1p10) requires this, but we're following the precedent set by gcc,
and hopefully nobody will ever ask about this again.
