Eric Fiselier 1faf289e27 [libcxx] Add atomic_support.h header to src that handles needed atomic operations. ...

Summary:
In some places in libc++ we need to use the `__atomic_*` builtins. This patch adds a header that provides access to those builtins in a uniform way from within the dylib source.

If the compiler building the dylib does not support these builtins then a warning is issued.

Only relaxed loads are needed within the headers. A singe function to do these relaxed loads has been added to `<memory>`.

This patch applies the new atomic builtins to `__shared_count` and `call_once`.

When building libc++, we use '"' as a delimiter instead of '<' when including libc++ header files. This is so that the dylib gets built with our headers; rather than the system-installed ones. We do this in most places already, just fixing a couple of inconsistent uses.
