Rong Bao a355eefc36 perf annotate: Use jump__delete when freeing LoongArch jumps 
Currently, the initialization of loongarch_jump_ops does not contain an
assignment to its .free field. This causes disasm_line__free() to fall
through to ins_ops__delete() for LoongArch jump instructions.

ins_ops__delete() will free ins_operands.source.raw and
ins_operands.source.name, and these fields overlaps with
ins_operands.jump.raw_comment and ins_operands.jump.raw_func_start.
Since in loongarch_jump__parse(), these two fields are populated by
strchr()-ing the same buffer, trying to free them will lead to undefined
behavior.

This invalid free usually leads to crashes:

This patch adds the missing free() specialization in loongarch_jump_ops,
which prevents disasm_line__free() from invoking the default cleanup
function.
