Alkis Evlogimenos af2de4848e 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).

Chris Lattner cb185a34bb Simplify code a bit, don't go off the end of the block, now that the current 
block we are in might be empty

Chris Lattner 4ffd4443ce We were forgetting to add FP_REG_KILL instructions to basic blocks which will 
eventually get an assignment due to elimination of PHIs.

Chris Lattner e79e854c5c Refactor some code. In the mul - setcc folding case, we really care about 
whether this is the sign bit or not, so check unsigned comparisons as well.
