I'm curious if these make a difference once statically linking though
It's not, but until we are statically linking, perhaps they are still interesting.

-Bsymbolic-functions for libLLVM-13git.so and libclang-cpp.so was re-committed in https://reviews.llvm.org/D102090.
-Bsymbolic-functions is ignored when linking an executable.
-fno-semantic-interposition was committed separately today https://reviews.llvm.org/D102453. Most files are compiled with -fPIC and they get pessimization when compiled by GCC. -fno-semantic-interposition reclaims the lost performance.
ELF platforms get the benefits automatically, no need for additional CMake options.
