* config/cris/cris.c (cris_notice_update_cc): Check first
destination also against overlap with cc_status.value2 and second
destination against overlap with cc_status.value1. For overlaps,
clear overlapped value, don't just CC_STATUS_INIT.
* config/cris/cris.h (EXTRA_CONSTRAINT_T): Fix spacing and FIXME.
(LINK_SPEC): Remove whitespace at end of line.
