LoongArch: Discard extra spaces in objdump output

Browse Source 
Due to the formatted output of objdump, some instructions
that do not require output operands (such as nop/ret) will
have extra spaces added after them.

Determine whether to output operands through the format
of opcodes. When opc->format is an empty string, no extra
spaces are output.
