[analyzer] Decide on inlining destructors via EvalCallOptions.

[analyzer] Decide on inlining destructors via EvalCallOptions.

EvalCallOptions were introduced in r324018 for allowing various parts of
ExprEngine to notify the inlining mechanism, while preparing for evaluating a
function call, of possible difficulties with evaluating the call that they
foresee. Then mayInlineCall() would still be a single place for making the
decision.

Use that mechanism for destructors as well - pass the necessary flags from the
CFG-element-specific destructor handlers.

Part of this patch accidentally leaked into r324018, which led into a change in
tests; this change is reverted now, because even though the change looked
correct, the underlying behavior wasn't. Both of these commits were not intended
to introduce any function changes otherwise.
