Chuang-Yu Cheng 7e3b6f3bce Teaching SimplifyCFG to recognize the Or-Mask trick that InstCombine uses to ... reduce the number of comparisons. Specifically, InstCombine can turn: (i == 5334 || i == 5335) into: ((i | 1) == 5335) SimplifyCFG was already able to detect the pattern: (i == 5334 || i == 5335) to: ((i & -2) == 5334) This patch supersedes D21315 and resolves PR27555 (https://llvm.org/bugs/show_bug.cgi?id=27555). Thanks to David and Chandler for the suggestions!
