have existed already in another LiveInterval, but removed.

Tell the codegen emitter that specific operands are not to be encoded, fixing
JIT regressions w.r.t. pre-inc loads and stores (e.g. lwzu, which we generate
even when general preinc loads are not enabled).

clobber.  This allows LR8 to be save/restored correctly as a 64-bit quantity,
instead of handling it as a 32-bit quantity.  This unbreaks ppc64 codegen when
the code is actually located above the 4G boundary.

        movb (%eax), %al
        shrb $4, %al
        movl 4(%esp), %ecx

saving one cycle by eliminating a shift.
