Create minimal remap table for symbol binary search.
ELF symbols are not sorted by address. Create remap table
which reshuffles the indices into sorted-by-address order.
This saves over 6x of memory (the remap table needs just
uint32_t per entry, as opposed the FuncInfo cache entry).
ART symbols are sorted. Make use of that fact.
