Objects allocated after a call to __lsan_disable() will be treated as
live memory. Also add a ScopedDisabler.

Change the LSan lit test logic. Now "check-lsan" tests the leak
checking functionality in both standalone LSan and ASan.

Before this change, each module defined a weak_odr global __msan_track_origins
with a value of 1 if origin tracking is enabled, 0 if disabled. If there are
modules with different values, any of them may win. If 0 wins, and there is at
least one module with 1, the program will most likely crash.

With this change, __msan_track_origins is only emitted if origin tracking is
on. Then runtime library detects if there is at least one module with origin
tracking, and enables runtime support for it.

This CL enables thread support in LSan when used on top of ASan.

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.
