History
Chris Lattner 1dbfd48fa2 Significantly improve the documentation of the instcombine divide/compare 
transformation.  Also, keep track of which end of the integer interval overflows
occur on.  This fixes Transforms/InstCombine/2007-06-21-DivCompareMiscomp.ll
and rdar://5278853, a miscompilation of perl.
