At the moment, MI varobj assume that register values have a language. As 
result, if you try to look at values of $xmm1 in a C++ program, you'll find 
that this registers has a 'public' field -- which is not reasonable.

The attached patch causes MI to always force the C language for register 
values, so no special processing takes place. OK?

	always use C as the language.
