Remove the GetResultInst instruction. It is still accepted in LLVM assembly
and bitcode, where it is now auto-upgraded to ExtractValueInst. Also, remove

The IRBuilder still accepts multiple-value returns, and auto-upgrades them
to InsertValueInst instructions.

Learn IPConstProp to propagate arguments that are directly returned. Strictly
...
speaking these are not constant values. However, when a function always returns
one of its arguments, then from the point of view of each caller the return
value is constant (or at least a known value) and can be replaced.
