[cost] Add model of NSArray.index_of_object_passing_test Summary: This diff add a model of `NSArray.index_of_object_passing_test` in autoreleasepool size model. Worst case autorelease cost is "array size x cost of given test function (lambda)". Reviewed By: ezgicicek Differential Revision: D23785165 fbshipit-source-id: 95ec9700a

[preanalysis] Handle closure substitution in conditionals Summary: Specialized closure substitution was broken for conditionals: ``` void foo(dispatch_block_t block1){ if (x){ block1(); // not replaced with specialized implementation } } ``` The problem was that when substituting function calls, it only used memory state at the exit node, rather than at each program point. We could solve this by - reverting the domain change in D24418560 (https://github.com/facebook/infer/commit/c47911359ac9a207aa376f6641915fccca5b150e), i.e. collecting all possible mappings conservatively (e.g. switch the domain back to `Map`) - pass the `invariant_map` for substitutions at each program point. We go with the second option here. The closure substitution is still somewhat broken as exemplified by the following example: ``` void foo(dispatch_block_t block1){ dispatch_block_t local_block = block1; local_block(); // we don't substitute the call here } ``` Reviewed By: skcho Differential Revision: D24993962 fbshipit-source-id: ebadddb58

[preanalysis] Handle assigning blocks to locals in closure substitution Summary: Existing closure substitution only supported direct block calls to formals. The following didn't work since the domain was only keeping track of loads/calls from formals, but didn't support stores. ``` void foo(dispatch_block_t block1){ dispatch_block_t local_block = block1; local_block(); // we don't substitute the call here } ``` This diff adds support for assigning a block to a local variable so that we can specialize the above example. We now have a pair domain - existing mapping from ids to block vars - a new mapping from mangled to block specializations the latter allows us to update the mapping in local block assignment (via store).

[cost] Enable passing enumerator as paramter in ObjC Summary: This diff revises memory model of enumerator in ObjC to enable passing it as a parameter.

This diff simplifies the enumerator to have a similar value with `array->elements`, so its offset can be taken without the relation between enumerator and array to get them.

[cost] Increase autoreleasepool size when non-ARC call ARC Summary: This diff increases autoreleasepool size when * caller is non-ARC-compiled * callee is ARC-compiled * return type is a pointer to objc object To distinguish non-ARC-/ARC-compiled: * extended `translation_unit_decl_info` to have a boolean field `is_objc_arc_on` * then copied it to `ProcAttributes.t` for each procedures.

[cost] Ignore tagged pointers in autoreleasepool size Summary: This diff ignores tagged pointers in the autoreleasepool size, since they are not added to the autorelease pool. https://opensource.apple.com/source/objc4/objc4-781/runtime/objc-internal.h.auto.html Reviewed By: ezgicicek Differential Revision: D23626339 fbshipit-source-id: ba9ef4106

[cost] Use prefix convention not returning autoreleased object Summary: By naming convention, methods start with "alloc", "new", "copy", and "mutableCopy" return non-autoreleased object. Let's avoid raising issues in that case. Reviewed By: ezgicicek Differential Revision: D23565512 fbshipit-source-id: e7aa58ea9
