d9277f249b [meta] Introduce the InstructionGroupBuilder; 
This follows the rest of the code base data structures, where we have a
mutable data structure builder; once the data structure is constructed,
it's immutable.

This also makes the definition of instructions easier, and it paves the
way for defining immediate variants.

wrapper of the actual instruction's content.
