[X86][X87] Mark pseudo memory fold instructions as load/sideeffects (PR21160, PR34080, PR34454).
Match regular x87 memory fold instructions with load/sideeffects tags, to prevent the schedulers from re-ordering them across the fnstcw/fldcw sequences for truncating stores while they are still pseudo during the stack conversion pass.
