[ASan] Use llvm.global_ctors to insert init-order checking calls into ASan runtime.

Don't assume that dynamically initialized globals are all initialized from
_GLOBAL__<module_name>I_ function. Instead, scan the llvm.global_ctors and
insert poison/unpoison calls to each function there.

Patch by Nico Weber!
