Duncan Sands 922251757b Add a generic expansion transform: A op (B op' C) -> (A op B) op' (A op C) ... if both A op B and A op C simplify. This fires fairly often but doesn't make that much difference. On gcc-as-one-file it removes two "and"s and turns one branch into a select. llvm-svn: 122399		2010-12-22 13:36:08 +00:00
