c954cfeb57 Some uses of the preprocessor can result in multiple target regions on the
same line. Cases such as those in the associated lit tests, can now be
supported.

This adds a 'Count' field to TargetRegionEntryInfo to differentiate
regions with the same source position.

The OffloadEntriesInfoManager routines are updated to maintain a count of
regions seen at a location. The registration of regions proceeds that same as
before, but now the next available count is always determined and used in the
offload entry.

ba3f85390b [OpenMP] Add diagnostic for unterminated 'omp [begin] declare target'
Warns when end-of-file is reached without seeing all matching
'omp end declare target' directives. The diagnostic shows the
location of the related begin directive.

9b9d08111b Set rpath on openmp executables
Openmp executables need to find libomp and libomptarget at runtime.
This currently requires LD_LIBRARY_PATH or the user to specify rpath. Change
that to set the expected location of the openmp libraries in the install tree.

Whether rpath means rpath or runpath is system dependent. The attached test
shows that the Wl,--disable-new-dtags control interacts correctly with this feature.

The implicit rpath field is appended to any user specified ones which is ideal.
