Fix length attribute for casesi_load pattern.
Perl compilation was broken:
--->---
$ arc-linux-gcc -DPERL_CORE -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64 -matomic -pipe -mdiv-rem -Os -c -o perl.o perl.c
perl.s: Assembler messages:
perl.s:1271: Error: operand out of range (512 is not between -512 and 511)
--->---
Fix is taken from current development branch of GCC for ARC and will be a
part of the next release of ARC tools, so at that point patch should be dropped.

; Unlike the canonical tablejump, this pattern always uses a jump address,
