079e0819bc Fix PR14568: Avoid the DFA packetizer from making an invalid read
beyond array bounds.

No test case since I cannot reproduce an ICE with this bug. According
to Carlos -- the bug reporter -- a segfault occurs only when LLVM is
compiled with a specific version of GCC.

6f36fa981a Write llvm-tblgen backends as functions instead of sub-classes.
The TableGenBackend base class doesn't do much, and will be removed
completely soon.

ffbd0715fa Increment DFAStateEntryTable index for sentinel entry.
When adding the {-1, -1} entry to the DFAStateInputTable, we
need to increment the index used to populate the DFAStateEntryTable.
Otherwise, the entry table will be off by one for each transition
after the {-1, -1} entry. PR11908.
