I just took a look and it isn't that simple.  This code is used
for example to replace
  i32 = truncate 0x2374b48
with the first result of
  i32,ch = load 0x2356390, 0x2357188, 0x2356b88 <0x236ee80:0> alignment=4
This works fine right now.  It fails with ReplaceNodeWith because the
number of results differs.  It could be made to work by using a MergeValues
node to produce a node with one result out of the load, and similarly for
the other examples of this kind of thing.

Ciao,

Duncan.
