extern "C" declarations should be considered like global declarations
for mangling purposes.

This was leading to duplicate counts when a code region happened to
overlap exactly with an expansion. The combining behaviour only makes
sense for code regions.

What's going on here is that the ternary operator produces a std::string rvalue
that the StringRef points to. I'd hoped bugs like this were a thing of the past
with our asan testing but apparently this code path is only used when LLVM is
configured with a custom --with-c-include-dirs setting.

This comes up when we generate coverage for a function but don't end
up emitting the function at all - dead static functions or inline
functions that aren't referenced in a particular TU, for example. In
these cases we'd like to show that the function was never called,
which is trivially true.

This fixes PR22492, which is in response to CWG issue #1204.
Per the CWG issue 'contexpr' variables are now allowed in
for range loops.

CopyContext is necessary to safely get the XState, but LLDB doesn't currently
use the XState. CopyContext is available as of Windows 7 SP1, so it can't be
used on Vista. Furthermore, it requires the Windows 8 SDK it compile,
making the baseline for compiling and running LLDB higher than necessary.

Make CoverageMapping easier to create, so that we can write targeted
unit tests for its internals, and add a some infrastructure to write
these tests. Finally, add a simple unit test for basic functionality.

Summary:
This patch adds a lit option to enable color diagnostics when either `--param=color_diagnostics` is passed to LIT or `LIBCXX_COLOR_DIAGNOSTICS` is present in the environment.
My only concern with this patch is that GCC and Clang take different flags and that only GCC 4.9 and greater support `-fdiagnostics-color=always`
Does anybody have objections to this going in?

This adds support for JavaScript class definitions (again following
TypeScript & AtScript style). This only required support for
visibility modifiers in JS, everything else was already working.

This patch adds support for type annotations that follow TypeScript's,

Summary:
This patch introduces some black magic to detect const and volatile qualified function types such as `void () const`.
The patch works in the following way:
We first rule out any type that satisfies on of the following. These restrictions are important so that the test below works properly.
* `is_class<_Tp>::value`
* `is_union<_Tp>::value`
* `is_void<_Tp>::value`
* `is_reference<_Tp>::value`
* `__is_nullptr_t<_Tp>::value`
If none of the above is true we perform overload resolution on `__source<_Tp>(0)` to determine the return type.
* If `_Tp&` is well-formed we select `_Tp& __source(int)`. `_Tp&` is only ill formed for cv void types and cv/ref qualified function types.
* Otherwise we select `__dummy_type __source(...)`. Since we know `_Tp` cannot be void then it must be a function type.
let `R` be the returned from `__source<_Tp>(0)`.
We perform overload resolution on `__test<_Tp>(R)`.
* If `R` is `__dummy_type` we call `true_type __test(__dummy_type)`.
* if `R` is `_Tp&` and `_Tp&` decays to `_Tp*` we call `true_type __test(_Tp*)`. Only references to function types decay to a pointer of the same type.
* In all other cases we call `false_type __test(...)`.
`__source<_Tp>(0)` will try and form `_Tp&` in the return type. if `_Tp&` is not well formed the return type of `__source<_Tp>(0)` will be dummy type. `_Tp&` is only ill-formed for cv/ref qualified function types (and void which is dealt with elsewhere).

Summary:
These ISA's didn't add any instructions so they are almost identical to
Mips32r2 and Mips64r2. Even the ELF e_flags are the same, However the ISA
revision in .MIPS.abiflags is 3 or 5 respectively instead of 2.

Long story short: stop-the-world briefly resets SIGSEGV handler to SIG_DFL.
This breaks programs that handle and continue after SIGSEGV (namely JVM).
