tsan: improve "destroy of a locked mutex" reports 1. Allow to suppress by current stack. We generally allow to suppress by all main stacks. Current is probably the stack one wants to use to suppress such reports. 2. Fix last lock stack restoration. We trimmed shadow value by storing it in u32. This magically worked for the test that provoked the report on the main thread. But this breaks for locks in any other threads. llvm-svn: 331023 2018-04-27 16:59:35 +08:00			`mutex:suppress_this`
