Improves activerecord by about 1% on the interpreter:

Legend:
- after 1st itr: ratio of before/after time for the first benchmarking iteration.
- before/after: ratio of before/after time. Higher is better for after. Above 1 represents a speedup.

Improves YJIT by about 4%:

This speeds up the mail benchmark by about 7% on the interpreter:

YJIT is about 13% faster:

With verbopse mode (-w), the interpreter shows a warning if
a block is passed to a method which does not use the given block.
Warning on:
* the invoked method is written in C
* the invoked method is not `initialize`
* not invoked with `super`
* the first time on the call-site with the invoked method
(`obj.foo{}` will be warned once if `foo` is same method)
[Feature #15554]
`Primitive.attr! :use_block` is introduced to declare that primitive
functions (written in C) will use passed block.
For minitest, test needs some tweak, so use
ea9caafc07
for `test-bundled-gems`.
