Recent changes have left insn_crosses_page() more complicated than it needed to be: * it's only called from thumb_tr_translate_insn() so we know for certain that we're looking at a Thumb insn * the caller's check for dc->pc >= dc->next_page_start - 3 means that dc->pc can't possibly be 4 aligned, so there's no need to check that (the check was partly there to ensure that we didn't treat an ARM insn as Thumb, I think) * we now have thumb_insn_is_16bit() which lets us do a precise check of the length of the next insn, rather than opencoding an inaccurate check Simplify it down to just loading the first half of the insn and calling thumb_insn_is_16bit() on it.
