cris: Avoid format-string-related warnings in calls to error functions

These tweaks are installed to avoid build-warnings for
config/cris/cris.c, like:

x/gcc/config/cris/cris.c: In function 'const char* cris_op_str(rtx)':
x/gcc/config/cris/cris.c:728:23: warning: unquoted identifier or keyword \
'cris_op_str' in format [-Wformat-diag]

      |   ^~~~~~~~~~~

Not that I therefore agree that operators, identifiers and keywords
should have to be dressed up like this for internal error messages;
they were more readable without these garments, if only slightly so.

	* config/cris/cris.c: Quote identifiers in parameters to error
	and internal_error, and remove extraneous spaces with punctuation.
	* config/cris/cris.h (CRIS_ASSERT): When passing on stringified
	expression to internal_error, pass it as a parameter instead of
	appending it to the format part.
