Extreme Performance Drop in Mario Party 2 (and other Virtual Console games)

Description
[Mario Party 2]
[NAZE01]
[91837da646f7509910d2472ad81f9c8b]
[Extreme Stuttering during the whole game, tried all possible graphic backends, audio backends and options. Issue is there with default options, too.]
[Reproduction of this issue is very easy. When you skip the first cutscene, you get to the title screen. Press start there and Toad will make his "YEEAAH" scream. Just during this scream, when he starts to jump, the game will stutter for a second. Just when he lands, it will stutter again. Stutters like these happen throughout the game, it is really unplayable like this.]
[5.0-2852]
[PC specs: i7 3770k, GTX1070, 16GB RAM]
Is there any other relevant information? (e.g. logs, screenshots,
configuration files)
[This issue does not exist with older Dolphin versions. I tried 3.5 stable and it worked just fine with default settings.]

Addition: Bear in mind that the stutters during the beginning always happen during the exact same time, so it is perfectly reproducable and not random.

Whenever the issue is a regression, I request a bisect. Try various versions in between until you find the culprit if there is one.

I was curious and checked this out. Yeah, seems like something is going on, not sure what yet.

To make your Bisect Much easier, 5.0-142 is fine. So, we're down to a few thousand builds.
5.0-1752 is also fine. I'll do the bisect I guess since I'm already on my way.
5.0-1752 - good
5.0-2002 - good
5.0-2136 - good
5.0-2174 - good
5.0-2178 - bad
5.0-2224 - bad
Branch Following is at fault. https://dolphin-emu.org/download/dev/5da565a1a1b3b148a41a483e1052f31b5698cf3c/

Thank you for paying attention to this and finding the branch which was responsible. Wow! Never had such an awesome report for a bugreport.

We should do something about this before the next stable release, even if it just is to add a setting to disable branch following.

Branch following is disabled in the game INI for all Nintendo 64 Virtual Console releases nowadays. (Not the GC disc releases of N64 Zelda games, though.) https://dolphin-emu.org/download/dev/31bc01759378fdb1461373497d8e7c3f00129a36/
