merged.

register mapping or a stack slot mapping.

0d56008f53 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.

d1eaebef49 The simplifycfg pass should be able to turn stuff like: 
if (X == 4 || X == 7)
and
  if (X != 4 && X != 7)

into switch instructions.

743d0a1f83 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).
