Allow to compile with --yjit-stats support but not the full RUBY_DEBUG
RUBY_DEBUG have a very significant performance overhead. Enough that
YJIT with RUBY_DEBUG is noticeably slower than the interpreter without
RUBY_DEBUG.
This makes it hard to collect yjit-stats in production environments.
By allowing to collect JIT statistics without the RUBy_DEBUG overhead,
I hope to make such use cases smoother.
