tsan: disable getpwuid_r() and glob64() interceptors under tsan, because they cause interceptor recursion if user intercepts fopen()

Wrap macro invocations in braces to supress 'suggest braces around empty body in an ‘if’ statement' warning.

This time it's the full list scavenged from syscalls.h
Fixed return value type.

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

Pre- and post- hooks for linux syscalls. Not wired into anything, but exposed
through public interface.

Add a test for time().

[Sanitizer] fix TSan tests: remove global ctor from sanitizer_common, run load_shared_lib test only in lit

This was committed without tests and contains obvious bugs. That's not
acceptable. It broke address sanitizer for most programs using glob(3).

llvm-svn: 179054

Add a regression test for the case where such behavior helps TSan:
  1. race is reported in the main module
  2. new shared library is loaded
  3. race is reported in the shared library

[sanitizer] found a bug by code inspection: CHECK(a=b) instead of CHECK(a==b). Was puzzled why lint did not catch it. Turns out this check was disabled for asan source. fix all cases and enable the check

getpwnam, getpwuid, getpwnam_r, getpwuid_r, clock_getres, clock_gettime,
clock_settime, getitimer, setitimer, sigaction (MSan).

Currently the callback runs on the caller's stack. If this stack
contains values that have gone out of scope, and we are not super careful, those
values can propagate into global variables (the libc sigaction() in particular
has a side effect that can lead to this). This has caused false negatives in
leak checking code.

Changes: map a separate stack space for the tracer thread. Also, move some
globals into local scope (they had no business being global anyway).
