ThreadSanitizer supports suppression mechanism, which extends regular valgrind suppressions

Our extensions:

• Multiple stack traces for one suppression rule are supported. Each stack trace must be enclosed by curly braces. As always, { and } should be on lines of their own.
• Demangled C++ function names are supported.

Example of new syntax:

{
  suppression_name
  tool_name:warning_name
  {
    fun:mangled_function_name_wildcard
    obj:object_name_wildcard
    ...
    fun:demangled_function_name_wildcard
  }
  {
    ...
    fun:another_mangled_function_name_wildcard
  }
}

Specify it with --suppressions=<filename> flag.
