927ead9f75 YJIT: unify exits. Patch iseqs only when necessary 
* YJIT: unify exits. Patch iseqs only when necessary

This fixes the gotcha that returning YJIT_CANT_COPMILE for an
instruction at entry position leading to infinite loop.

Also, iseq patching is only done only when necessary, which should make
most exits faster.

* Now that exits are the same, return YJIT_CANT_COMPILE

5d834bcf9f YJIT: lazy polymorphic getinstancevariable 
Lazily compile out a chain of checks for different known classes and
whether `self` embeds its ivars or not.

* Remove trailing whitespaces

* Get proper addresss in Capstone disassembly

* Lowercase address in Capstone disassembly

Capstone uses lowercase for jump targets in generated listings. Let's
match it.

* Use the same successor in getivar guard chains

Cuts down on duplication

* Address reviews

* Fix copypasta error

* Add a comment

c15a577eda Make Blocks depend on BOPS 
When a BOP is redefined, the BOP redefinition callback will invalidate
any blocks that depend on BOPS.  This allows us to eliminate runtime
checks for BOP redefinition.
