Method changeObjectDeclarationType

src/bin2llvmir/utils/ir_modifier.cpp:724–790

* Change @c val declaration to @c toType. Only the object type is changed, * not its usages. Because of this, it is not safe to use this function alone. * This function is not public, i.e. accessible from other modules. * @param objf Object file for this object -- needed to initialize it values. * @param val Value which type to change. * @param toType Type to change it to. * @param init

 * value's type can be mutated, or a new object if it cannot.
