(1) Testing CF_LAST_IO is a hold-over from since before ba3e7926691 ("icount: clean up cpu_can_io at the entry to the block"). Several targets still have this test. (2) Testing singlestep is superfluous, as it doesn't mean anything besides limiting max_insns to 1. (3) Not testing page crossing for CONFIG_USER_ONLY is wrong, because mmap and mprotect can change page permissions. It's a very uncommon case wrt executables, but it's still wrong. (4) Not testing page crossing for non-mmu targets (where page permissions literally cannot change) is not currently wrong, but will be after the breakpoint changes. (5) When the TB does cross two pages, considering non-page crossing from the second page is not currently wrong, but will be after the breakpoint changes. Changes for v2: * Fix aarch32 ISB, SB insns vs single-stepping. * Drop use_goto_tb for aarch32 * Retain use_goto_tb for aarch64.
