Chris Lattner f125dc0e49 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. llvm-svn: 18817		2004-12-12 05:53:50 +00:00
