You're more likely to find lua or sometimes python in modern games than assembly. Scripting has become a big part of many games, and lua has found its niche by virtue of being relatively light weight and quite easy to interface with from C/C++.
I don't think I've seen any assembly that was actually enabled in the games I've worked on in the last five years, though I do know where there's a tiny bit in my current project that's #if'd for older environments. That's just stuff like atomic operations that every modern compiler provides built-ins for now.
