[LVI][CVP] LazyValueInfoImpl::solveBlockValueBinaryOp(): use no-wrap flags from `add` op
Summary:
This was suggested in https://reviews.llvm.org/D69277#1717210
In this form (this is what was suggested, right?), the results aren't staggering
(especially since given LVI cross-block focus)
this does catch some things (as per test-suite), but not too much:
