Louis Dionne a00290ed10 [libc++] Fix allocate_shared when used with an explicitly convertible allocator
When the allocator is only explicitly convertible from other specializations
of itself, the new version of std::allocate_shared would not work because
it would try to do an implicit conversion. This patch fixes the problem
and adds a test so that we don't fall into the same trap in the future.

Louis Dionne 19d57b5c42 [libc++] Refactor allocate_shared to use an allocation guard
This commit is a step towards making it easier to add support for arrays
in allocate_shared. Adding support for arrays will require writing multiple
functions, and the current complexity of writing allocate_shared is
prohibitive for understanding.
