opcodes: xtensa: display loaded literal value
Display literal value loaded with l32r opcode as a part of disassembly. This significantly simplifies reading of disassembly output. 2020-04-23 Max Filippov <jcmvbkbc@gmail.com> opcodes/ * xtensa-dis.c (print_xtensa_operand): For PC-relative operand of l32r fetch and display referenced literal value.
