Alexey Samsonov 9c85927012 [Sanitizer] Make StackTrace a lightweight reference to array of PCs, and 
introduce a BufferedStackTrace class, which owns this array.

Summary:
This change splits __sanitizer::StackTrace class into a lightweight
__sanitizer::StackTrace, which doesn't own array of PCs, and BufferedStackTrace,
which owns it. This would allow us to simplify the interface of StackDepot,
and eventually merge __sanitizer::StackTrace with __tsan::StackTrace.

Test Plan: regression test suite.

Sergey Matveev 2d3f8d7840 [lsan] Unbreak standalone LSan's initialization by making it more like ASan's. 
No longer allow interceptors to be called during initialization, use the preinit
array (instead of initializing at the first call to an intercepted function) and
adopt the calloc() hack from ASan.
