Another additional error check for invalid Mach-O files for the
obsolete load commands.
Again the philosophy of the error checking in libObject for
Mach-O files, the idea behind the checking is that we never
will return a Mach-O file out of libObject that contains unknown
things the library code can’t operate on. So known obsolete
load commands will cause a hard error.
Also to make things clear I have added comments to the
values and structures in Support/Mach-O.h and
Support/MachO.def as to what is obsolete.
As noted in a TODO in the code, there may need to be a
non-default mode to allow some unknown values for well
structured Mach-O files with things like unknown load
load commands. So things like using an old lldb on a newer
Mach-O file could still provide some limited functionality.
