j_xxx functions are being given symbols #8475

Description

@ElykDeer

Version and Platform:

  • Binary Ninja Version: 6.1.10533-dev
  • Edition: Ultimate
  • OS: OSX
  • OS Version: 26.5.2
  • CPU Architecture: M3

Bug Description:
Functions without symbols (in the file header) are being given symbols (in bv.symbols) if they're j_* functions.

Steps To Reproduce:
Please provide all steps required to reproduce the behavior:

  1. Open any binary
  2. Run [sym for sym in bv.symbols if sym.startswith('j_')]

Expected Behavior:
These functions shouldn't have symbols in bv.symbols (see correctly missing sub_ function below with the j_ to it). As discussed during the hackathon, function.symbol is confusing enough without them also spilling into the global symbols.

If applicable, please add screenshots/video recording here to help explain your problem.
