Use the code model instead of some arbitrary number for cross-section branches

The idea of a fixed cross-section branch distance isn't really
representative of the cross-section branch issue. The linker
can place two sections any distance away from each other
so long as both fit within the program address range specified
by the code model. Use the code model instead.
