Noticed while testing other things:

gcc/config/fr30/fr30.c: In function ‘fr30_move_double’:
gcc/config/fr30/fr30.c:885: warning: ISO C90 forbids mixed declarations and code
gcc/config/fr30/fr30.c:886: warning: ISO C90 forbids mixed declarations and code
gcc/config/fr30/fr30.c:883: warning: unused variable ‘dregno’

dregno is truly dead, its last use was deleted by:

	PR target/34174
	* config/fr30/fr30.c (fr30_move_double): Sanitize mem->reg case. Copy
	the address before it is clobbered.

Fixed like so.  Committed.

	* config/fr30/fr30.c (fr30_move_double): Delete `dregno' and extra
	semicolons.
