Sungkeun Cho	270918fea7	[cost] Remove dead field Struct.subs ... Summary: This diff removes a dead field `Struct.subs`, which was used in heuristics finding methods from sub-classes. Reviewed By: ezgicicek Differential Revision: D22945346 fbshipit-source-id: 4b3bf0093	5 years ago
Sungkeun Cho	161b3484f9	[cost] Revert subclass lookup heuristics ... Summary: In Cost/Inferbo checkers, it tried to find a subclass with heuristics when a method of interface or abstract class is called. While it makes preciser analysis results in general, sometimes introduced tricky FPs since the behavior of the heuristics depends on targets. This diff revert the heuristics to suppress the FPs.

Sungkeun Cho	534149ff52	[cost] Find method of interface or abstract class ... Summary: To find a method in non-abstract sub-classes, this diff applies the same heuristics of inferbo. * If the class is an interface: Find its unique sub-class and apply the heuristics recursively. * If the class is an abstract class: Find/use its own summary if possible. If not found, find one (arbitrary but deterministic) summary from its sub-classes. * Otherwise: Find its own summary.
