Peter Eisentraut ee4859123e jit: Use opaque pointers in all supported LLVM versions. 
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.
