Can't we simply arrange for cached_reg_restore_code to

Not really, -1 already means something else.  No doubt this can be fixed, but
it's no one-liner so can certainly wait for 4.6.


Ah.  In which case for 4.5 it might be best to just
rearrange a pattern in i386.md to the top.  Perhaps
something like "blockage" or "nop" would be best.
