[analyzer] Fix body farm for Obj-C++ properties

Authored by vsavchenko on Mar 23 2021, 8:54 AM.



When property is declared in a superclass (or in a protocol),
it still can be of CXXRecord type and Sema could've already
generated a body for us. This patch joins two branches and
two ways of acquiring IVar in order to reuse the existing code.
And prevent us from generating l-value to r-value casts for
C++ types.

I'm not familiar with Objective-C.

At this point Prop may contain a completely unrelated property decl. It doesn't necessarily correspond to the IVar or have the right name. We keep it after the end of the loop and use it later. This doesn't sound right.

It is actually intentional. To reuse that bit of code that used to be under if(!IVar) condition.

Set Prop and IVar at the same time
