Comment at: llvm/test/CodeGen/X86/add-cmov.ll:158-159
 ; CHECK-NEXT:    retq
   %s = select i1 %b, i64 42, i64 2147483648
   %r = add i64 %offset, %s
   ret i64 %r
----------------
Would transforming this into
```
  %tval = add i64 %offset, 42
  %fval = add i64 %tval, 2147483606
  %r = select i1 %b, i64 %tval, i64 %fval
```
be a win? https://godbolt.org/z/rYjzePnr4
