intel: Avoid the need for most overflow checks by using a scratch page.
The overflow checks were all thoroughly untested, and a bunch of the ones I'm deleting were pretty broken. Now, in the case of overflow, you just decode data of 0xd0d0d0d0, and instr_out prints the warning message instead. Note that this still has the same issue of being under-tested, but at least it's one place instead of per-packet. A couple of BUFFER_FAIL uses are left where the length to be decoded could be (significantly) larger than a page, and the decode didn't just call instr_out (which doesn't dereference data itself unless it's safe).
