[cost] add inferbo model for NSArray Summary: As title Reviewed By: ezgicicek Differential Revision: D22390462 fbshipit-source-id: bd9157874

codetoanalyze/objc/performance/NSArray.m, nsarray_empty_array_constant, 3, CONDITION_ALWAYS_FALSE, no_bucket, WARNING, [Here]
[cost] add objc test for NSArray and NSMutableArray Summary: Add objc test for ```NSArray``` and ```NSMutableArray```. ```NSMutableArray``` is a subclass of ```NSArray```. For documentation of ```NSArray```, https://developer.apple.com/documentation/foundation/nsarray?language=objc For documentation of ```NSMutableArray```, https://developer.apple.com/documentation/foundation/nsmutablearray?language=objc The underlying mechanism for ```NSMutableArray``` is quite complicated. It changes the underlying data structure during runtime, so it is possible to have say O(log n) complexity for accessing element in array. (See here https://opensource.apple.com/source/CF/CF-855.11/CFArray.h) However, this is unlikely to happen if the engineer does not abuse the usage of the class ```NSMutableArray``` according to at least two ios engineers. So here the complexity is set to match the normal expectation of the complexity. Reviewed By: ezgicicek Differential Revision: D22041277 fbshipit-source-id: c27f43167
