at least as big as the mach header to be identified as a Mach-O file and make sure smaller files are not identified as a Mach-O files but as unknown files. Also fix identify_magic() so it looks at all 4 bytes of the filetype field when determining the type of the Mach-O file. Then fix the macho-invalid-header test case to check that it is an unknown file and make sure it does not get the error for object_error::parse_failed. And also update the unit tests. llvm-svn: 258883
