gh-105775: Convert LOAD_CLOSURE to a pseudo-op (#106059) 
This enables super-instruction formation,
removal of checks for uninitialized variables,
and frees up an instruction.

gh-102676: Add more convenience properties to `dis.Instruction` (#103969) 
Adds start_offset, cache_offset, end_offset, baseopcode,
baseopname, jump_target and oparg to dis.Instruction.

Also slightly improves the disassembly output by allowing
opnames to overflow into the space reserved for opargs.

Change FOR_ITER to have the same stack effect regardless of whether it branches or not.
Performance is unchanged as FOR_ITER (and specialized forms jump over the cleanup code).

gh-92228: disable the compiler's 'small exit block inlining' optimization for blocks that have a line number (GH-94592) 
Inlining of code that corresponds to source code lines, can make it hard to distinguish later between code which is only reachable from except handlers, and that which is reachable in normal control flow. This caused problems with the debugger's jump feature.

This PR turns off the inlining optimisation for code which has line numbers. We still inline things like the implicit "return None".
