ccbe603869 Ban rematerializable instructions with side effects.
TableGen infers unmodeled side effects on instructions without a
pattern.  Fix some instruction definitions where that was overlooked.

Also raise an error if a rematerializable instruction has unmodeled side
effects. That doen't make any sense.

0a951fba75 V_SET0 has no side effects.
TableGen will mark any pattern-less instruction as having unmodeled side
effects. This is extra bad for V_SET0 which gets rematerialized a lot.

This was part of the cause for PR11125, but the real bug was fixed
in r141923.

a80444f88d Add value numbers when spilling dead defs.
When spilling around an instruction with a dead def, remember to add a
value number for the def.

The missing value number wouldn't normally create problems since there
would be an incoming live range as well.  However, due to another bug
we could spill a dead V_SET0 instruction which doesn't read any values.

The missing value number caused an empty live range to be created which
is dangerous since it doesn't interfere with anything.

This fixes part of PR11125.
