Chris Lattner 96a86b2993 If a variable can only hold two values, and is not already a bool, shrink it 
down to actually BE a bool.  This allows simple value range propagation
stuff work harder, deleting comparisons in bzip2 in some hot loops.

This implements GlobalOpt/integer-bool.ll, which is the essence of the
loop condition distilled into a testcase.
