Summary:
Thread id will be added to VRerort. Having thread here is useful.
This is also common place for logging for all sanitizers, so I can use this in
common test.

This patch addresses two issues:
* It turned out that suspended thread may have dtls->dtv_size == kDestroyedThread (-1)
and LSan wrongly assumes that DTV is available. This leads to SEGV when LSan tries to
iterate through DTV that is invalid.
* In some rare cases GetRegistersAndSP can fail with errno 3 (ESRCH). In this case LSan
assumes that the whole stack of a given thread is available. This is wrong because ESRCH
can indicate that suspended thread was destroyed and its stack was unmapped. This patch
properly handles ESRCH from GetRegistersAndSP in order to avoid invalid accesses to already
unpapped threads stack.

Current code tries to find the dynamic TLS header to the left of the
TLS block without checking that it's not a static TLS allocation.
