8385112: [lworld] 8369044 fix missing for arm and ppc

[PeyaPeyaPeyang]

Hi there,

I (re)checked the other TemplateTable::_return implementations as well.

ARM looks like it was simply missed, so I added the same check for _return and _return_register_finalizer there as well¹.

For PPC, I left it unchanged.
Its _return implementation already emits a StoreStore barrier in the later switch when state == vtos.
Since also _return_register_finalizer is a vtos return, that case is already covered there.

The other implementations look good to me.
