  Log Message:
  -----------
  [InstCombine] remove multi-use add demanded constant fold

This was originally part of D133788. There are no visible
regressions. All of the diffs show a large unsigned constant
becoming a small negative constant. This should be better
for analysis (and slightly less compile-time) and codegen.
