Summary: missing wideInt Tcl_ObjType

Initial Comment:

When I build and use Tcl on a platform where
TCL_WIDE_INT_IS_LONG gets #define'd,
like my Linux/Alpha machine, the consequence
is that there is no Tcl_ObjType named "wideInt"
registered in that Tcl library.

This means that an extension writer cannot
reliably Tcl_ConvertToType either to or from
the "wideInt" type across platforms.  Instead
extensions are required to do a rather complex
conditionalizing on TCL_WIDE_INT_IS_LONG.

Would be much nicer if the Tcl library always
defined the "wideInt" Tcl_ObjType, but just
made sure it did the right thing on different
platforms.

The most recent example is the TIP 111
implementation.  I cannot test this on my
Linux/Alpha box, because parts of it just
assume that comparisons against &tclWideIntType
are possible.  That's the internal version of
the exported description above.
