Now that we have 1024B slots, we can store up to 126 fields inline. Objects larger than this are rare if not non-existent, hence we can get rid of the `malloc` path for imemo/fields and simply transition to `TOO_COMPLEX`. This additionally allows to shrink `attr_index_t` from 16 to 8B. Note: the ZJIT "ivar on extended" tests are renamed as "complex" because "extended" AKA malloc allocated imemo/fields no longer exists. They're now complex fields, AKA st tables. rb_class_allocate_instance: start as complex when over max_fields If `RCLASS_MAX_IV_COUNT` is over `max_fields`, allocating a large slot to end up transitioning to `TOO_COMPLEX` is wasteful. We might as well start as complex directly.
The `too_` prefix wasn't consistently used and just make the thing longer for no benefit.
For consistency.
The interpreter may fire the `rb_zjit_invalidate_no_ep_escape` callback multiple times for the same ISEQ. The first one will process all patch points so subsequent processing is unnecessary. Consuming the no-EP-escape patch points on first invocation avoids redundant repeated computation.
