GH-104909: Split LOAD_ATTR_INSTANCE_VALUE into micro-ops

[markshannon]

• Issue: Split opcodes into micro-ops #104909

[markshannon]

I've change the code generator to allow micro-ops to be shared between instructions.

@gvanrossum Why was that prohibited?

I've change the code generator to allow micro-ops to be shared between instructions.

@gvanrossum Why was that prohibited?

It was just a piece of technical debt, nothing deep. There was some complication and I was initially lazy and put a data structure on the micro-op itself instead of associating it with the connection beween the macro and the op.
