objects
The reference counter for global objects marked with declare target is INF. This patch prevents the runtime from incrementing /decrementing INF refcounts. Without it, the map(delete: global_object) directive actually deallocates the global on the device. With this patch, such a directive becomes a no-op.

This patch implements the libomptarget runtime interface for OpenMP 5.0
declare mapper functions. The declare mapper functions generated by
Clang will call them to complete the mapping of members.
kmpc_mapper_num_components gets the current number of components for a
user-defined mapper; kmpc_push_mapper_component pushes back one
component for a user-defined mapper.

infinite loop on removing non-mapped pointer-with-object.
Added test to check that libomptarget does not cause infinite loop when
trying to unmap the pointer-with-object data that was not previously
mapped.

erase() invalidates the iterator and returns a new one pointing
to the following element. The code now follows the example at
https://en.cppreference.com/w/cpp/container/map/erase.
(The added testcase crashes without this patch.)
