Unify the 386 entry point code as much as possible. The main function could not be unified because on Windows 386 it is called _main. Putting main in asm_386.s caused multiple definition errors when using the external linker. Add the _lib entry point to various operating systems. A future CL will enable c-archive/c-shared mode for those targets. Fix _rt0_386_windows_lib_go--it was passing arguments as though it were amd64.
