This adds a method to blocks to get outgoing ids, then uses the outgoing
ids to generate a graphviz graph. Two methods were added to the Block
object. One method returns an id for the block, which is just the
address of the underlying block. The other method returns a list of
outgoing block ids. We can use Block#id in conjunction with
Block#outgoing_ids to construct a graph of blocks

* Implement send with blocks
Not that much extra work compared to `opt_send_without_block`.
Moved the stack over flow check because it could've exited after changes
are made to cfp.
* rename oswb counters
* Might as well implement sending block to cfuncs
* Disable sending blocks to cfuncs for now
* Reconstruct interpreter sp before calling into cfuncs
In case the callee cfunc calls a method or delegates to a block.
This also has the side benefit of letting call sites that sometimes are
iseq calls and sometimes cfunc call share the same successor.
* only sync with interpreter sp when passing a block

Introduce a new macro `ADD_COMMENT(cb, comment)` that records a comment
for the current write position in the code block.

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.

Make it lazy and add a hash specialization in addition to the array
specialization.

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
