Max Filippov 847a647320 target/xtensa: disas/xtensa: fix coverity warnings 
Coverity warnings CID 1385146, 1385148 1385149 and 1385150 point that
xtensa_opcode_num_operands and xtensa_format_num_slots may return -1
even when xtensa_opcode_decode and xtensa_format_decode succeed. In that
case unsigned counters used to iterate through operands/slots will not
do the right thing.
Make counters and loop bounds signed to fix the warnings.

Max Filippov 5a6539e627 target/xtensa: implement disassembler 
Add disas/xtensa.c and use libisa for instruction decoding/opcode name
lookup.
