Move some common code in hipe_pack_constants
All backends (e.g. arm, ppc, sparc, x86) share the same code for the following functions: * find_const/2, * mk_data_relocs/2, and * slim_sorted_exportmap/3 This commit moves those definitions (along with some helper functions) in misc/hipe_pack_constants.erl and adds the appropriate specs. This is a structural change; no change in semantics intented.
