mpageandGitHub 053c285f6b gh-130704: Strength reduce LOAD_FAST{_LOAD_FAST} (#130708) 
Optimize `LOAD_FAST` opcodes into faster versions that load borrowed references onto the operand stack when we can prove that the lifetime of the local outlives the lifetime of the temporary that is loaded onto the stack.

 		98e855fcc1 gh-119180: Add LOAD_COMMON_CONSTANT opcode (#119321) 
The PEP 649 implementation will require a way to load NotImplementedError
from the bytecode. @markshannon suggested implementing this by converting
LOAD_ASSERTION_ERROR into a more general mechanism for loading constants.

This PR adds this new opcode. I will work on the rest of the implementation
of the PEP separately.
