Declare the family of AnnotateIgnore[Read,Write][Begin,End] TSan annotations in compiler-rt/test/tsan/test.h so that we don't have to declare them separately in every test that needs them. Replace usages. Leave usages that explicitly test the annotation mechanism: thread_end_with_ignore.cpp thread_end_with_ignore3.cpp llvm-svn: 371446
