Constructs a unsynchronized_pool_resource.

1-4) Constructs a unsynchronized_pool_resource using the specified upstream memory
resource and tuned according to the specified options. The resulting object holds a
copy of upstream but does not own the resource to which upstream points.
The overloads not taking opts as a parameter uses a default constructed instance of
pool_options as the options. The overloads not taking upstream as a parameter uses
the return value of std::experimental::pmr::get_default_resource() as the upstream
memory resource.
5) Copy constructor is deleted.


opts - a pool_options struct containing the constructor options
upstream - the upstream memory resource to use


1-4) Throws only if a call to the allocate() function of the upstream resource
throws. It is unspecified if or under what conditions such a call takes place.
