[ruby/mmtk] Implement fast path for bump pointer allocator

2025-12-21T02:55:12+00:00

Adding a fast path for bump pointer allocator can improve allocation
performance.

For the following microbenchmark with MMTK_HEAP_MIN=100MiB:

    10_000_000.times { String.new }

Before:

    810.7 ms ±   8.3 ms    [User: 790.9 ms, System: 40.3 ms]

After:

    777.9 ms ±  10.4 ms    [User: 759.0 ms, System: 37.9 ms]
