previous we may generate two line_info record for the first insn in a function: the line info based subprogram line and the line info based on the debugloc of the first insn. This is confusing. Now let us just generate one. for the first insn of the function, if the debugloc is available, use that to generate the line info. Otherwise, use the subprogram line to generate a line info record for BTF.
