This patch adds support to ARM for custom lowering of the llvm.{u|s}add.with.overflow.i32 intrinsics for i32/i64. This is particularly useful for handling idiomatic saturating math functions as generated by InstCombineCompare. Test cases included. rdar://14853450 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@208435 91177308-0d34-0410-b5e6-96231b3b80d8
