Compute a cost of the given call instruction.

Compute the cost of calling function F with return type RetTy and argument types Tys. F might be nullptr, in this case the cost of an arbitrary call with the specified signature will be returned. This is used, for instance, when we estimate call of a vector counterpart of the given function.

Parameters
FCalled function, might be nullptr.
RetTyReturn value types.
TysArgument types.
Returns
The cost of Call instruction.
