This has been on the books as a wanted-future-addition to GDB for ages;
pending someone with an active need for it to spec out the details. 
However, the really interesting question to me is: does anyone know of
hardware where we would want a debugger to be able to perform reads of
more than one size on a particular address?

Otherwise, this can be handled completely without user interface, based
on a device memory map description.
