i386: Rename crotate attribute to inv_rotate

The crotate code attribute maps a rotation operation to its
inverse direction (rotate <-> rotatert). Since "counter rotate"
does not accurately describe this relationship, rename the
attribute to inv_rotate.

No functional change intended.

gcc/
	* config/i386/i386.md (crotate): Rename to inv_rotate.
	Update all uses accordingly.
