Delete unused tb_invalidate_page_range
tb_invalidate_page_range() was intended to be used to invalidate an area of a TB which the guest explicitly flushes from i-cache. However, QEMU detects writes to code areas where TBs have been generated, so his has never been useful. Delete the function, adjust callers.
