Always enable caching on transition32; backup/restore cr0 on call32

Always enable caching at start of 32bit code and always make sure the
paging flag is off.  Because this alters the cr0 register, perform a
backup and restore of it when using call32().

Also, rename get/setcr0() to cr0_read/write() to more closely match
other register access functions.
