Evgeniy Stepanov 755eb32a39 [sanitizer] Add syscall handlers to ASan and TSan runtimes. 
ASan checks addressability of syscall arguments. TSan does nothing for now.

Evgeniy Stepanov 9fb82357dc [sanitizer] More syscall handler placeholders. 
This time it's the full list scavenged from syscalls.h
Fixed return value type.

Timur Iskhodzhanov 664ec5d7a8 Finally drop the 'static' from INLINE and ALWAYS_INLINE 
The ALWAYS_INLINE doesn't have static on POSIX anyways since r178341; the INLINE is only used in .h files, so shouldn't have been 'static' in the first place

Chandler Carruth 2b3c00eec7 Revert r179012: "[msan] Intercept glob()." 
This was committed without tests and contains obvious bugs. That's not
acceptable. It broke address sanitizer for most programs using glob(3).

Alexander Potapenko 32efd25b93 [libsymbolized] If we can't find an address in the list of shared libraries, try to reload it. 
Add a regression test for the case where such behavior helps TSan:

  2. new shared library is loaded
  3. race is reported in the shared library
