ASan calls this function only for global variables (not functions). It
is needed because
we use a different machinery to pass global names to ASan runtime - we
register globals
by a call from instrumented code, which also tells runtime the
(mangled) global name.

Hi!
With the new tsan tests, I've noticed that libbacktrace symbolization
doesn't work when the binary is a PIE.
The problem is that in that case we obviously can't use base_address
of 0, the PIE typically will not have 0 bias, that is actually the sole
point of PIEs that their base address is ran
