Duncan Sands ebef48ea4b Speculatively revert commit 121905 since it looks like it might have broken the ... dragonegg self-host buildbot. Original commit message: Add an InstCombine transform to recognize instances of manual overflow-safe addition (performing the addition in a wider type and explicitly checking for overflow), and fold them down to intrinsics. This currently only supports signed-addition, but could be generalized if someone works out the magic constant formulas for other operations. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@121965 91177308-0d34-0410-b5e6-96231b3b80d8		2010-12-16 09:40:54 +00:00
