Write the identifier table into the PCH file as an on-disk hash table

that also includes the contents of the IdentifierInfo itself (the
various fields and flags, along with the chain of identifiers visible
at the top level that have that name).

We don't make any use of the hash table yet, except that our
identifier ID -> string mapping points into the hash table now.
