[OMPD] The LLVM OMPD library has the wrong names for the "release" functions

[jdelsign]

The OpenMP v5.0 spec (and OpenMP omp-tools.h header) use "ompd_rel_" as the prefix for the "release" functions. However, the LLVM OMPD library uses "ompd_release_" as the prefix for those functions (which is what OMPD 3.1 used). The OMPD DLL defines the following functions:

  ray23{jdelsign}103: nm /collab/usr/global/tools/ompd/ppc64le-ray//lib/libompd.so | grep ompd_rel
  000000000001c100 T ompd_release_address_space_handle
  00000000000206f0 T ompd_release_display_control_vars
  000000000001df20 T ompd_release_parallel_handle
  000000000001ef30 T ompd_release_task_handle
  000000000001c8d0 T ompd_release_thread_handle
  ray23{jdelsign}104: 

All of those functions should be renamed to conform to the OMP v5.0 standard.
