I'm not quite sure whether you're looking for a way to reorganize the
compiler's intermediate representation to speed up the compilation
process or for a way to automatically reorganzie data structures that
are used in the compiled program to speed up the execution time. If
you're looking for the latter you might be interested in the following

Thomas Kistler and Michael Franz. Automated Layout of Data Members for
Type-Safe Languages. Technical Report No. 98-22, Department of
Information and Computer Science, University of California, Irvine,
September 1998.
