ThreadSanitizer. - Modified DRD's error reporting code such that it does no longer let the Valgrind core print the Valgrind thread ID but that it now prints the DRD thread ID and name. Updated expected output files where necessary. - Modified drd/test/Makefile.am such that the tests using gcc's built-in functions for atomic memory access such that these are only compiled when the gcc version in use supports these built-in functions. git-svn-id: svn://svn.valgrind.org/valgrind/trunk@10186
