inline assembly for STOP instruction clobbers CCR

Description

The STOP instruction modifies the CPU's condition-code
register. Therefore, 'cc' should be added to the asm's
clobber-list.

It is unlikely that this really causes problems in this
case because the surrounding C-code doesn't really check
any conditions...
