Eliminate ASan stack-buffer-underflow FP in GC_mark_and_push_stack (E2K)

According to the contract, the object p (the argument of
GC_mark_and_push_stack) has passed a preliminary pointer validity
check, but we do not definitely know whether it is valid.

* mark.c (GC_mark_and_push_stack): Add GC_ATTR_NO_SANITIZE_ADDR
attribute.
