always create a new jump table.  The intention was to avoid merging jump
tables in SelectionDAGBuilder, and to wait for the branch folding pass to
merge tables.  Unfortunately, the same getJumpTableIndex() method is also
used to merge tables in branch folding, so as a result of this change
branch tables are never merged.  Worse, the branch folding code is expecting
getJumpTableIndex to always return the index of an existing table, but with
this change, it never does so.  In at least some cases, e.g., pr6543, this
creates references to non-existent tables.

I've fixed the problem by adding a new createJumpTableIndex function, which
will always create a new table, and I've changed getJumpTableIndex to only
look at existing tables.

the macro definitions and macro instantiations that are found
during preprocessing. Preprocessing records are *not* generated by
default; rather, we provide a PPCallbacks subclass that hooks into the
existing callback mechanism to record this activity.

The only client of preprocessing records is CIndex, which keeps track
of macro definitions and instantations so that they can be exposed via
cursors. At present, only token annotation uses these facilities, and
only for macro instantiations; both will change in the near
future. However, with this change, token annotation properly annotates
macro instantiations that do not produce any tokens and instantiations
of macros that are later undef'd, improving our consistency.

Preprocessing directives that are not macro definitions are still
handled by clang_annotateTokens() via re-lexing, so that we don't have
to track every preprocessing directive in the preprocessing record.

Performance impact of preprocessing records is still TBD, although it
is limited to CIndex and therefore out of the path of the main compiler.
