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).

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

[libsanitizer] Run the callback on a separate stack in StopTheWorld.
...
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).

The reason why this simple change is needed is that I am trying to set up a
quick cmake/ninja based buildbot and apple-clang does not support using the
sanitizers currently.
The default behavior follows exactly what was there before implying that no ones
builds should be affected at all.
