Calixte Denizet	0da37bedc2	[compiler-rt] Reduce the number of threads in gcov test to avoid failure ... Summary: Patch in D78477 introduced a new test for gcov and this test is failing on arm: - http://lab.llvm.org:8011/builders/clang-cmake-thumbv7-full-sh/builds/4752/steps/ninja%20check%202/logs/stdio - http://lab.llvm.org:8011/builders/clang-cmake-armv7-full/builds/10501/steps/ninja%20check%202/logs/stdio So try to fix it in reducing the number of threads.

Calixte Denizet	bec223a9bc	[profile] Don't crash when forking in several threads ... Summary: When forking in several threads, the counters were written out in using the same global static variables (see GCDAProfiling.c): that leads to crashes. So when there is a fork, the counters are resetted in the child process and they will be dumped at exit using the interprocess file locking. When there is an exec, the counters are written out and in case of failures they're resetted.
