4191045be4 Mark the invoke call instruction as implicitly defining the callee-saved registers.
The callee-saved registers cannot be live across an invoke call because the
control flow may continue along the exceptional edge. When this happens, all of
the callee-saved registers are no longer valid.

610fc64d78 An instruction's operands aren't necessarily instructions or constants. They
could be arguments, for example.

a31553dbf7 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.

d7827f928d 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.

98e48aef6f 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.

667bf19c57 Avoid undefined behavior in negation in LSR. Patch by Ahmed Charles.

release the stack segment and reset the stack pointer. Place the code in its own
