nhaehnle added a dependency: D48014: AMDGPU: Use generic tables instead of SearchableTable.

This allows us to access rich information about MIMG opcodes from C++ code.
Simplifying the mapping between equivalent opcodes of different data size
becomes quite natural.

This also flattens the MIMG-related class and multiclass hierarchy a little,
and collapses together some of the scaffolding for sample and gather4 opcodes.
