[DynInst_API:] new-parallel-parsing branch

There was a problem with the examples dir; it was unpopulated for some 
reason so I repopulated it from master.  With that I then got (Fedora 28):
[ 44%] Linking CXX shared library libparseAPI.so
CMakeFiles/parseAPI.dir/src/debug_parse.C.o: In function 
`Dyninst::ParseAPI::parsing_printf_int(char const*, ...)':
/work/scox/dyninst/src/parseAPI/src/debug_parse.C:65: undefined 
reference to `omp_get_thread_num'
collect2: error: ld returned 1 exit status
make[2]: *** [parseAPI/CMakeFiles/parseAPI.dir/build.make:1160:

make[1]: *** [CMakeFiles/Makefile2:1082: 
parseAPI/CMakeFiles/parseAPI.dir/all] Error 2
make: *** [Makefile:130: all] Error 2

To get around that I added this to parseAPI/CMakeLists.txt

set(OPENMP_LIBRARIES gomp)
# scox added OPENMP_LIBRARIES
target_link_private_libraries(parseAPI ${Boost_LIBRARIES} 
${TBB_LIBRARIES} ${OPENMP_LIBRARIES} tbbmalloc)
and got past that.  However I still hit the problem building the 
examples (issue #459)
[ 93%] Linking CXX executable codeCoverage
/usr/bin/ld: cannot open output file codeCoverage: Is a directory
collect2: error: ld returned 1 exit status

I pulled in the #459 patch which resolves the above but hit a different 
problem building examples that I'll look at.
