LLVM's opaque pointer change began in LLVM 14, but remained optional until LLVM 16. When commit 37d5babb added opaque pointer support, we didn't turn it on for LLVM 14 and 15 yet because we didn't want to risk weird bitcode incompatibility problems in released branches of PostgreSQL. (That might have been overly cautious, I don't know.) Now that PostgreSQL 18 has dropped support for LLVM versions < 14, and since it hasn't been released yet and no extensions or bitcode have been built against it in the wild yet, we can be more aggressive. We can rip out the support code and build system clutter that made opaque pointer use optional.
