add uadd_ov/usub_ov to apint, consolidate constant folding logic to use the new APInt methods. Among other things this implements rdar://8501501 - llvm.smul.with.overflow.i32 should constant fold which comes from "clang -ftrapv", originally brought to my attention from PR8221. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@116457 91177308-0d34-0410-b5e6-96231b3b80d8
