e5db7dc4c6 Implement: test/Regression/Transforms/SimplifyCFG/switch_create.ll 
This turns code like this:
  if (X == 4 | X == 7)
and
  if (X != 4 & X != 7)
into switch instructions.

90da2d674f The simplifycfg pass should be able to turn stuff like: 
if (X == 4 || X == 7)
and
  if (X != 4 && X != 7)

into switch instructions.

e532a181c7 Use the new LLVM is_class template instead of the boost one, allowing us to 
remove our dependency on boost!  Thanks to Reid Spencer for making this possible!

template.  Thanks go out to Reid Spencer for skillfully extracting this
from boost!

9b103024ef Refactor rewinding code for finding the first terminator of a basic 
block into MachineBasicBlock::getFirstTerminator().

This also fixes a bug in the implementation of the above in both
RegAllocLocal and InstrSched, where instructions where added after the
terminator if the basic block's only instruction was a terminator (it
shouldn't matter for RegAllocLocal since this case never occurs in
practice).

whether this is the sign bit or not, so check unsigned comparisons as well.
