Alexey Bataev 622e46156d [OPENMP]Fix PR46824: Global declare target pointer cannot be accessed in target region. 
Need to map the base pointer for all directives, not only target
data-based ones.
The base pointer is mapped for array sections, array subscript, array
shaping and other array-like constructs with the base pointer. Also,
codegen for use_device_ptr clause was modified to correctly handle
mapping combination of array like constructs + use_device_ptr clause.
The data for use_device_ptr clause is emitted as the last records in the
data mapping array.

It applies only for global pointers.
