The removal of this would break the `clang/test/Analysis/region-store.c:79:3` test case. It's intentional.
The `hasBody` (awkwardly though), sets the parameter (`Definition`) to the definition decl of the function decl if it has definition.

I could have used the `if (const auto *Def = CallExprDecl.getDefinition()) Definition = Def;` but that would have been longer to spell, along with a controlflow statement.
