We add two records in sil_block to specify a witness table record and a method entry record. Out of the four entry types, only "Method" is handled in this commit. Two records are also added to sil_index_block to search for a specific witness table given a unique identifier. The interface lookupWitnessTable is not implemented yet. Right now, we serialize a witness table only when sil-serialize-all is on and deserialize all witness tables in the module when sil-link-all is on. rdar://15722175 Swift SVN r13000
