General memory improvements to decrease GC pressure and frequency.

Pool big arrays and objects that are created and deleted often.

Skip data copies when they aren't needed.

Inline flag checks to skip unneeded allocations.

From my testing the performance is about the same, but the GC frequency is much lower and collection is faster causing less and smaller spikes.
