When ASan is enabled, treat conversions to unsafe.Pointer as an escaping operation. In this way, all pointer operations on the stack objects will become operations on the escaped heap objects. As we've already supported ASan detection of error memory accesses to heap objects. With this trick, we can use -asan option to report errors on bad stack operations. Add test cases. Updates #44853.
