GH-118093: Turn some DEOPT_IFs into EXIT_IFs

[brandtbucher]

This allows us to stitch new traces onto these side-exits, giving us better handling of polymorphism for attribute loads and calls.

About 1% faster. Stats show a notable (~28%) drop in _DEOPT instructions and moderate increases in call and attribute load uops, as expected.

• Issue: Increase fraction of code executed by tier 2. #118093

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by switching back to a branch.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -c with the switch command. Example:

  git switch -c <new-branch-name>

Or undo this operation with:

  git switch -

Turn off this advice by setting config variable advice.detachedHead to false
