The bit added by commit a56e7b660 is still there in
src/backend/jit/llvm/Makefile:

+# LLVM 14 produces deprecation warnings.  We'll need to make some changes
+# before the relevant functions are removed, but for now silence the warn=
ings.
+ifeq ($(GCC), yes)
+LLVM_CFLAGS +=3D -Wno-deprecated-declarations
+endif

Surely we don't need this anymore?  I tried removing it locally
and didn't see any such warnings (with Red Hat's llvm 20.1.8).
