Anshuman Dasgupta 3923e286cd 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.

Jakob Stoklund Olesen e6aed139f0 Write llvm-tblgen backends as functions instead of sub-classes. 
The TableGenBackend base class doesn't do much, and will be removed
completely soon.

Brendon Cahoon e9b60aaf1c 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.
