Erik Eckstein 2db6f3d213 SIL: remove multiple result values from SILValue
As there are no instructions left which produce multiple result values, this is a NFC regarding the generated SIL and generated code.
Although this commit is large, most changes are straightforward adoptions to the changes in the ValueBase and SILValue classes.
