[RuntimeDyld] Allow processRelocationRef to process more than one relocation entry at a time.

Some targets require more than one relocation entry to perform a relocation.
This change allows processRelocationRef to process more than one relocation
entry at a time by passing the relocation iterator itself instead of just
the relocation entry.
