Use llvm::sys::path::native instead of llvm::sys::fs::normalize_separators.

llvm::sys::path::native has a superset of the functionality and this was the
only use of llvm::sys::fs::normalize_separators.

Change __ENVIRONMENT_MAC_OS_X_VERSION_MIN_REQUIRED__ for versions > 10.9.

The previous encoding only allowed a single digit for the minor version
number. This changes it to use 2 digits for both the minor version and the
revision number.

Extend tautological pointer compare and pointer to bool conversion warnings to
macro arguments.

Previously, these warnings skipped any code in a macro expansion.  Preform an
additional check and warn when the expression and context locations are both
in the macro argument.

The most obvious case not caught is passing a pointer directly to a macro,
i.e 'assert(&array)' but 'assert(&array && "valid array")' is caught.  This is
because macro arguments are not typed and the conversion happens inside the
macro.

Add -link-cxx-sanitizer driver flag.

Summary:
This flag can be used to force linking of CXX-specific parts
of sanitizer runtimes into the final executable. It gives more precise
control than --driver-mode=g++ and comes handy when user links several
object files with sanitized C++ code into an executable, but wants
to provide libstdc++ himself, instead of relying on Clang dirver's
behavior.

Simplify ownership of ExplodedGraph in the CoreEngine by removing unique_ptr indirection.

Summary: I was going to fix the use of raw pointer ownership in "takeGraph" when I realized that function was unused and the whole ExplodedGraph could just be owned by value without the std::unique_ptr indirection at all.

Predefine IB_DESIGNABLE and IBInspectable macros. <rdar://problem/17441860>

These macros are used as markers for Interface Builder and need to be defined

Add tests for coverage mapping generation.

This patch adds the tests for the coverage mapping generation. 
Most of the tests check the mapping regions produced by 
the generator, and one checks the llvm IR.

Remove some transient raw pointer ownership in ClangAttrEmitter::createArgument

This function might be a bit easier if it were split in two with a lot
of early returns - and that setOptional bit in the outer function, but
anyway.

Refactor the module map file used for uniquing a module name out of

class Module. It's almost always going to be the same as
getContainingModule() for top-level modules, so just add a map to cover
the remaining cases.  This lets us do less bookkeeping to keep the
ModuleMap fields up to date.

Revert "Add tests for coverage mapping generation."

I reverted one of the added tests from r215261 in r215274, since it
was failing on quite a few bots. It looks like this wasn't sufficient,
as we're still getting failures on windows, like the following:

    http://bb.pgr.jp/builders/ninja-x64-msvc-RA-centos6/builds/5378

I'm reverting this entire commit so the bots aren't blocked on these
failures.

This reverts commit r215261.
