constant pools with regular intervals. However if we try to reuse

[libc++] Implement exception_ptr on Windows

Summary:
This patch implements exception_ptr on Windows using the `__ExceptionPtrFoo` functions provided by MSVC.

The `__ExceptionPtrFoo` functions are defined inside the C++ standard library, `msvcprt`, which is unfortunate because it requires libc++ to link to the MSVC STL. However this doesn't seem to cause any immediate problems. However to be safe I kept all usages within the libc++ dylib so that user programs wouldn't have to link to MSVCPRT as well.

Note there are still 2 outstanding exception_ptr/nested_exception test failures.

* `current_exception.pass.cpp` needs to be rewritten for the Windows exception_ptr semantics which copy the exception every time.
* `rethrow_if_nested.pass.cpp` need investigation. It hits a stack overflow, likely from recursion.

This patch also gets most of the `<future>` tests passing as well.

Be a little more permissive in DynamicLoaderMacOS::CanLoadImage

If we can't find the "is dyld locked" symbol, assume it is safe
to load the image unless we only have 1 image loaded - in which case
we are in _dyld_start and it is definitely NOT safe.

Also add a little better errors to that function, and better logging
in SBProcess.cpp.
