I am not saying I am particularly happy with how it was implemented, but 
you should take a look at the "dynamic_size_dwarf_expr" members of the 
RegisterInfo struct 
<https://github.com/llvm-mirror/lldb/blob/master/include/lldb/lldb-private-types.h#L57>. 
These were added to support some variable length registers on mips, and 
it sounds like they could be useful here too.
