[foreign-memaccess] [Rev 01] RFR: 8244128: Allocations larger than MAX_ALIGN can fail to be sliced to proper size.

[Jorn Vernee]

> Hi,
> 
> This patch fixes a problem where the MemorySegment resulting from an allocation was not always sliced to the requested
> size, when the allocation code was manually up-sizing the allocation in order to perform manual alignment of the
> returned MemorySegment, but the initial allocation turned out to be aligned any ways.  Thanks,
> Jorn

  Slice allocated segments when alignedSize != byteSize (since alignedSize != buf might be false accidentally)
