I once noticed that gprof had such a feature, one of it's outputs was an ordered list of functions that you pass to the linker which then clustered them together.
If I remember the general technique of reordering procedures to improve load time has been called 'page tuning' because the idea is to get commonly used functions in the same page of memory. It also has the happy benifit of reducing real ram usage for common cases.
