Mike Rice e1ca7b614f [OPENMP] Create non-const ident_t objects.
Currently ident_t objects are created const when debug info is not
enabled, but the libittnotify libray in the OpenMP runtime writes to
the reserved_2 field (See __kmp_itt_region_forking in
openmp/runtime/src/kmp_itt.inl).  Now create ident_t objects non-const.

Alexey Bataev 62a4cb06a9 [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 b363813543 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)
