Kostya Serebryany 895ff83e47 [tsan] make calloc crash instead of returning 0 on overflow (controlled by the allocator_may_return_null flag)

Sergey Matveev d109eb052b [tsan] Move some suppressions-related code to common. 
Factor out code to be reused in LSan. Also switch from linked list to vector.

Sergey Matveev 954c6ef10f [sanitizer] Move GetThreadStackAndTls from TSan to sanitizer_common. 
Move this function to sanitizer_common because LSan uses it too. Also, fix a bug
where the TLS range reported for main thread was off by the size of the thread
descriptor from libc (TSan doesn't care much, but for LSan it's critical).

Dmitry Vyukov 2429b02770 tsan: move traces from tls into dedicated storage at fixed address
