Thank you all. That makes sense... Agreeing that the POINTER
version is applicable only in some cases, looking only at the
non-POINTER cases, for ldc2, a static array is faster, making
the "arbitrary" 16MiB limit a performance issue. For ldc2,
static array is about 40% faster:

Actually, the STATIC version is always faster on my machine
(Core i5 5200U), in both dmd and ldc2 cases
In dmd's case, the non-STATIC version seems to evaluate the loop
condition (arr.length) **everytime**.
