pgsql: Fix illegal attribute propagation in LLVM JIT.
Fix illegal attribute propagation in LLVM JIT. Commit 72559438 started copying more attributes from AttributeTemplate to the functions we generate on the fly. In the case of deform functions, which return void, this meant that "noundef", from AttributeTemplate's return value (a Datum) was copied to a void type. Older LLVM releases were OK with that, but LLVM 18 crashes. Update our llvm_copy_attributes() function to skip copying the attribute for the return value, if the target function returns void. Thanks to Dmitry Dolgov for help chasing this down. Back-patch to all supported releases, like 72559438.
