    [DOC] Add back Rust 1.85.0 requirement to NEWS.md (#15728)

    * [DOC] Add back Rust 1.85.0 requirement to NEWS.md

    Addresses k0kubun's review in https://github.com/ruby/ruby/pull/15711#issuecomment-3690541074

    NEWS.md serves both CRuby developers as well as end-users. As the
    release date closes in, it probably gets seen by more users than
    core developers (on the blog for example).

    Most users probably don't build Ruby by hand, and instead that is
    abstracted through tools like ruby-install or a package manager.
    For some users these tools may install pre-built binaries where
    they exist, in which case the Rust requirement doesn't apply. In
    other instances, the tools merely automate the build, in which case
    the correct rustc version is required to enable support.

    It is also a little confusing to talk about "enabling support for
    the JIT during the build" vs "enabling the JIT at runtime".

    This copy attempts to balance all of the above and hopefully gets
    the correct points across all intended audiences.

    * Apply suggestion from k0kubun

    ZJIT: Don't mark control-flow opcodes as invalidating locals (#15694)

    jump, branchif, etc don't invalidate locals in the JIT; they might in the interpreter because they can execute arbitrary code, but the JIT side exits before that happens.

    [ruby/mmtk] Implement Ruby heap

    This heap emulates the growth characteristics of the Ruby default GC's
    heap. By default, the heap grows by 40%, requires at least 20% empty
    after a GC, and allows at most 65% empty before it shrinks the heap. This
    is all configurable via the same environment variables the default GC
    uses (`RUBY_GC_HEAP_FREE_SLOTS_GOAL_RATIO`, `RUBY_GC_HEAP_FREE_SLOTS_MIN_RATIO`,
    `RUBY_GC_HEAP_FREE_SLOTS_MAX_RATIO`, respectively).

    The Ruby heap can be enabled via the `MMTK_HEAP_MODE=ruby` environment
    variable.

    Compared to the dynamic heap in MMTk (which uses the MemBalancer algorithm),
    the Ruby heap allows the heap to grow more generously, which uses a bit
    more memory but offers significant performance gains because it runs GC
    much less frequently.

    We can see in the benchmarks below that this Ruby heap heap gives faster
    performance than the dynamic heap in every benchmark, with over 2x faster
    in many of them. We see that memory is often around 10-20% higher with
    certain outliers that use significantly more memory like hexapdf and
    erubi-rails. We can also see that this brings MMTk's Ruby heap much
    closer in performance to the default GC.
