It appears that glibc 2.13 has the same thread descriptor size as 2.11,
...
bump up the inflection point to 2.14. If someone can tell me how to
actually figure out value for this, that would be awesome.
Anyways, this takes me to one ASan failure, one LSan failure, and three
TSan failures for 'check-all' on Linux.

[sanitizer] Change the way GetThreadStackAndTls() obtains the thread descriptor address.

Instead of using arch_prctl(ARCH_GET_FS), read the address from the
tread descriptor itself. This lets us avoid sandboxing issues. Also,
GetThreadStackAndTls() can now be implemented on i386.
