[ARC] Disassembler: fix LIMM detection for short instructions.
The ARC (short) instructions are using a special register number to
indicate is the instruction uses a long immediate (LIMM). In the case
of short instruction, this LIMM indicator depends on the ISA version
used. Thus, for ARCv1 processors, the LIMM indicator is 0x3E, the same
value used in "long" instructions. However, for the ARCv2 processors,
this LIMM indicator is 0x1E.
This patch fixes the LIMM detection for ARCv1 ISA and adds two tests.
