Artem Dergachev 7d4694547a [analyzer] Escape pointers stored into top-level parameters with destructors. ... Writing stuff into an argument variable is usually equivalent to writing stuff to a local variable: it will have no effect outside of the function. There's an important exception from this rule: if the argument variable has a non-trivial destructor, the destructor would be invoked on the parent stack frame, exposing contents of the otherwise dead argument variable to the caller. If such argument is the last place where a pointer is stored before the function exits and the function is the one we've started our analysis from (i.e., we have no caller context for it), we currently diagnose a leak. This is incorrect because the destructor of the argument still has access to the pointer. The destructor may deallocate the pointer or even pass it further. Treat writes into such argument regions as "escapes" instead, suppressing spurious memory leak reports but not messing with dead symbol removal.
