perf annotate: Fix instruction association and parsing for LoongArch

In the perf annotate view for LoongArch, there is no arrowed line
pointing to the target from the branch instruction. This issue is
caused by incorrect instruction association and parsing.

This patch fixes instruction association issues, such as associating
branch instructions with jump_ops instead of call_ops, and corrects
false instruction matches. It also implements branch instruction parsing
specifically for LoongArch. With this patch, we will be able to see the
arrowed line.
