12:52 AM Ruby Revision 7a09df45 (git): Name the `iseq->body->param` struct and update bindings for JITs

This will make reading the parameters nicer for the JITs. Should be
no-op for the C side. alanwu (Alan Wu)

12:52 AM Ruby Revision 07ddb0ed (git): ZJIT: Read `iseq->body->param` directly instead of through FFI

Going through a call to a C function just to read a bitfield was a

11:14 PM Ruby Revision 2cd792a1 (git): ZJIT: Fix assertion failure when profiling VM_BLOCK_HANDLER_NONE

As can be seen in vm_block_handler_verify(), VM_BLOCK_HANDLER_NONE is

when seen instead of crashing. alanwu (Alan Wu)

09:35 PM Ruby Revision 89849f3b (git): ZJIT: Support JIT-to-JIT calls to callees with optional parameters

* Correct JIT entry points for optionals so each optional start with nil
before their initialization routine runs. Establish
`jit_entry_points[filled_opts_num]` gives the appropriate entry point
* Correct number of HIR block parameters ... alanwu (Alan Wu)
