The patch fixes a server compiler crash that happens in a very rare condition, described here. A key attribute of the server compiler IR is that an instruction must dominate all its inputs. However, in the function remix_address_expressions(), this property was violated and caused a crash in a later split if transformation.
Thanks to Chuck Rasbold and Tom Rodriguez.
