Hi,

To_prepare_to_store can make process record control the register
change operation before set the value of regcache in function
"regcache_raw_write". But it can't get the regnum.
So I change it to "to_store_registers". It can get the regnum. And if
record want cancel the operation the operation. It can invalidate the
value with itself.

	* record.c (record_beneath_to_prepare_to_store): Removed.
