Owen Anderson aefeb448a9 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.

Fixes <rdar://problem/8558713>.
