asan: Fix missing FakeStack flag cleanup
The FakeStack flag is not zeroed out when can_store_by_pieces()
returns false. Over time, this causes FakeStack::Allocate() to perform
the maximum number of loop iterations, significantly slowing down the
instrumented program.

* asan.cc (asan_emit_stack_protection): Always zero the flag
unless it is cleared by the __asan_stack_free_N() libcall.
