[pulse] Loosen fieldname comparison in state Summary: When C and C++ code handle a common struct typed value, the struct type is handled as a `CStruct` in the C code, but as a `CppClass` in the C++ code. On the other hand, `Fieldname.t` contains a string of field and **the struct type**. As a result, even if a same field is accessed in C and C++ code, the accessed fieldnames are different. ``` void callee_in_c(struct s* x) { x->a = 3; } void caller_in_cpp() { struct s x; x.a = 5; callee_in_c(&x); // HERE } ``` For example, in the above code, `caller_in_cpp` sets the field `a` as 5, then calls `callee_in_c`, which sets the field `a` as 3. However, at `HERE`, the value of `x` in Pulse is `{a -> 5, a -> 3}`, because the two fieldnames are addressed as different ones. To avoid the issue, this diff loosens the fieldname comparison in Pulse. Reviewed By: jvillard Differential Revision: D26000812 fbshipit-source-id: 77142ebda
