Reverts patches providing octet support in dwarf
Reverts "dwarf2: Align relocation within .debug_line section" commit 204f543cae7a5dc908264b49d558191d0ceb989c, Reverts "dwarf2: Pad size of .debug_line section." commit 145c4477d239fef4e31a457ff8a1ba7153e9a448, Reverts "dwarf2: Use octets for .debug_line prologue" commit 38c24f42c97af59ad83505ed735e689c63d3ca45, Mostly reverts "dwarf2: Use octets for dwarf2 headers" commit 7235427998571b6d8267e7ac72a52d7b082f4c2b, Mostly reverts "Symbols with octets value" commit d18d199917337537713f9fc4b7ae4d6568f740cf. * dwarf2dbg.c (out_set_addr): Revert 2019-03-13 change. (out_debug_line, out_debug_aranges, out_debug_info): Likewise. * symbols.h (symbol_set_value_now_octets, symbol_octets_p): Remove. * symbols.c (struct symbol_flags): Remove member sy_octets. (symbol_temp_new_now_octets): Don't set symbol_flags::sy_octets. (resolve_symbol_value): Revert: Return octets instead of bytes if sy_octets is set. (symbol_set_value_now_octets): Remove. (symbol_octets_p): Remove.
