Currently LOAD_COMMON_CONSTANT only loads 7 not-so-common constants and does so fairly inefficiently.

It could be improved in two ways:

• Add some more constants, especially None, but also "", True, False and -1
• Make the constants that it does load both statically allocated and immortal to avoid the pointer chasing and incref operation. Only any and all would need changing.

After some consideration, I think it best to leave the common constants table per interpreter, and not statically allocate them.

• The changes to any and all may be breaking.
• We also need to handle AssertionError and NotImplementedError will be tricky to make static

They should all be immortal though, and stored as _PyStackRefs not PyObject *s.
