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).

With this change, __internal_*stat always expect a "struct stat *" argument.
This avoids stat/stat64 caller-side confusion (sanitizer_common tests already
made this mistake), and allows the use of __internal_fstat() as a drop-in
replacement for libc's fstat().

Some flags that are common to ASan/MSan/TSan/LSan have been moved to
sanitizer_common.

There isn't a speedup when using unbuffered I/O. It slows it down in fact.

llvm-svn: 181060

Use unbuffered I/O. This reduces the runtime by about half. Our implementation is now only about 5 times slower than gcc's.

The fread / fwrite calls were happening for each timer. However, that could be
pretty expensive for a large number of timers. Instead, read and write the
timers in one call.

This gives ~10% speedup in compilation time.

This change adds ASan runtime option "strict-init-order" (off by default)
that makes init-order checker bark if global initializer accesses any global from different
translation unit (even if the latter is already initialized). strict init-order checking
doesn't play well with, e.g. LLVM registration machineries, and causes issue 
https://code.google.com/p/address-sanitizer/issues/detail?id=178.

[TSan] Allocate fd table in user heap instead of using internal allocator. We need this to catch races on fds.
