The os_log helper functions are linkonce_odr and supposed to be uniqued across TUs, so attachine a DW_AT_decl_line on it is highly misleading. By setting the function decl to implicit, CGDebugInfo properly marks the functions as artificial and uses a default file / line 0 location for the function. rdar://problem/63450824 Differential Revision: https://reviews.llvm.org/D80463
