Collect statistics about binding allocations / local variable set
...
This commit collects statistics about how many binding objects are
allocated as well as the number of local variables set on bindings.
Statistics are output along with other YJIT stats. Here is an example
of the output:
```

Running RailsBench allocates 195 binding objects but doesn't set any
local variables.

Fix improper use of st_foreach_with_replace
...
Replacing the key was only okay if the new key hashes to the same thing
as the old key. That doesn't hold for YJIT's table when the keys move.

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

Include ruby/ruby.h before vm_core.h
...
This is how vm.c does it, and if we don't follow it in yjit
compilation units, rb_vm_t would have a conflicting size.

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.
