- Clean up the code generated by tablegen:
  * AddToISelQueue now takes one argument.
  * ComplexPattern matching condition can now be shared.
  * Eliminate passing unnecessary arguments to emit routines.
  * Eliminate some unneeded SDOperand declarations in select routines.
  * Other minor clean ups.
- This reduces foot print slightly: X86ISelDAGToDAG.o is reduced from 971k
  to 823k.

The PPC code emitter was expecting the offset to be number of instructions, not
number of bytes. This fixes a whole bunch of JIT failures.

Final commit for this bug. This removes the last EH holdouts in LLVM
and turns off exception support by using the -fno-exceptions option. This
leads to the following reduction in library and executable sizes:
