The stats are not obviously better.

This PR reduces misses in LOAD_ATTR specializations, but it also increases the number of deferred operations due to shadowing.

Both STORE_ATTR_WITH_HINT and LOAD_ATTR_WITH_HINT are reduced in number considerably, being replaced by STORE_ATTR_INSTANCE_VALUE and LOAD_ATTR_INSTANCE_VALUE.

From this, it appears that this PR does what it aims to do. It also appears that it would be worth improving our handling of shadowed attributes.

I plan to fix the shadowing issue before merging this, so that it becomes a clear improvement
