Crash with debugging clang++/llvm18

[sbromberger]

Summary

I'm trying to debug a file built with clang++18. Helix crashes with no entry found for key.

This might be related to #11483.

Reproduction Steps

I tried this:

1. hx
2. (set breakpoint)
3. launch debug target / binary / testmv
   I expected this to happen:

Debugger to launch

Instead, this happened:

Helix crashed.
