Sergey Matveev b5769dbb86 [lsan] Introduce print_suppressions flag. 
Introduce a flag to either always or never print matched suppressions.
Previously, matched suppressions were printed unconditionally if there were
unsuppressed leaks. Also, verbosity=1 no longer has the semantics of "always
print suppressions and summary".

Alexey Samsonov 25d010a98d [Sanitizer] Always initialize a Symbolizer (even if 'symbolize' is false). 
If 'symbolize' flag is not set, we still want to transform virtual address
to module+offset pair in the call to Symbolizer::SymbolizeCode().
See https://code.google.com/p/address-sanitizer/issues/detail?id=251 for
more details.

Sergey Matveev 7237879926 [lsan] Introduce __lsan_(un)register_root_region(). 
Add an interface for telling LSan that a region of memory is to be treated as a
source of live pointers. Useful for code which stores pointers in mapped memory.

Evgeniy Stepanov 59bb0878e2 [msan] Tweak gethostbyname_r interceptor some more. 
This is covered by msan_test depending on glibc version and/or resolver setup.

Evgeniy Stepanov cb98c5f6f0 [msan] Relax gethostbyname_r test condition. 
Apparently, its return value depends on the glibc version.

Evgeniy Stepanov 43fc44007d [msan] Fix gethostbyname_r and similar interceptors. 
*h_errno is written not on success, but on failure.
In fact, it seems like it can be written even when return value signals
success, so we just unpoison it in all cases.

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

  pthread_getattr_np   <<< not reentable
  GetThreadStackTopAndBottom
  __interceptor_realloc

This may break builds where others added code relying on these patches,

which fix the failures.

Reverts the following commits:
r168306: "[asan] support x32 mode in the fast stack unwinder. Patch by H.J. Lu"
r168356: "[asan] more support for powerpc, patch by Peter Bergner"
