Evgeniy Stepanov cd07898cf8 [msan] Get stack limits with pthread_create interceptor. 
Before we did it lazily on the first stack unwind in the thread.
It resulted in deadlock when the unwind was caused by memory allocation
inside pthread_getattr_np:
  pthread_getattr_np   <<< not reentable
  GetThreadStackTopAndBottom
  __interceptor_realloc
  pthread_getattr_np

Evgeniy Stepanov 65562f5281 [msan] Fix origin of deallocated memory. 
MSan poisons deallocated memory but it used to give it an invalid origin value,
resulting in confusing reports. This change associates deallocation stack trace
with such memory.

Note that MSan does not have quarantine, and use-after-free detection is very
limited.
