* Guard `lit_dump_literals` with `JERRY_ENABLE_LOG` (both in source and in header). * Change `printf`s to `JERRY_DLOG`. * Make `lit_dump_literals` be called in `lit_finalize` (it was dead code). * Remove its duplicate declaration from lit-literal.h JerryScript-DCO-1.0-Signed-off-by: Akos Kiss akiss@inf.u-szeged.hu
