[sanitizer] speedup deadlock detector for the case when we destroy a mutex that has never been locked

llvm-svn: 202487

Introduce DDetector interface between the tool and the DD itself.
It will help to experiment with other DD implementation,
as well as reuse DD in other tools.

[sanitizer] do not acquire a global mutex in deadlock detector when dealing with Unlock (it is essentially a thread-local operation)

this fixes obscure false positives
see the comments and the test for details

[asan] *experimental* implementation of invalid-pointer-pair detector (finds when two unrelated pointers are compared or subtracted). This implementation has both false positives and false negatives and is not tuned for performance. A bug report for a proper implementation will follow.

asan_device_setup is a utility that prepares a device to run code built with
ASan. Essentially, it installs ASan runtime library into the system. For this
reason, it has to be at a predictable relative path from the runtime library
itself. We also plan to distribute this utility, packaged with runtime library
and maybe llvm-symbolizer, to the users.

This is done mostly for consistency, because this setting is normally overridden in cmake.

* Fix bash scripts to work on FreeBSD (patch by Viktor Kutuzov)
* Update locations of lit tests in check_lint script.

This should fix the issues with `make check-asan` on OS X.

[asan] Fix for size_t in Asan's new and delete operators on x64 FreeBSD in 32-bit mode, only for FreeBSD <= 9.2; patch by Viktor Kutuzov

[sanitizer] fix epoch handling in deadlock detector (before the fix, we could have had edges from locks in the previous epoch to locks in the current epoch)

llvm-svn: 202118

[asan] simplify the code that compute the shadow offset; get rid of two internal flags that allowed to override it. The tests pass, but still this change might break asan on some platform not covered by tests. If you see this, please submit a fix with a test.

AdjustStackSizeLinux() is used in Lsan, Tsan and Msan non-Linux-specific code so it seems it should have more generic name and moved to a common scope.
Renamed to AdjustStackSize.
