Alexey Bataev 540e4d95f1 [OPENMP] Change linkage of offloading symbols to support dropping
offload targets.

Changed the linkage of omp_offloading.img_start.<triple> and omp_offloading.img_end.<triple> symbols from external to external weak to allow dropping of some targets during linking.

Alexey Bataev 4da33cdc63 The patch adds support for the new map interface between clang and libomptarget. The changes in the interface are the following:
device IDs are now 64-bit integers (as opposed to 32-bit)
map flags are 64-bit long (used to be 32-bit)
mappings for partially mapped structs are now calculated at compile time and members of partially mapped structs are flagged using the MEMBER_OF field
Support for is_device_ptr on struct members was dropped - this functionality is not supported by the OpenMP standard and its implementation is technically infeasible (however, use_device_ptr on struct members works as a non-standard extension of the compiler)

Alexey Bataev 5e9ecae5b3 [OPENMP, NVPTX] Fix linkage of the global entries.
The linkage of the global entries must be weak to enable support of
redefinition of the same target regions in multiple compilation units.
