RFR: 8321786: SegmentAllocator:allocateFrom(ValueLayout, MemorySegment, ValueLayout, long, long) spec mismatch in exception scenario [v6]

Tue Dec 12 15:29:46 UTC 2023

> This PR proposes to change the specification for some methods that take `long` offsets so that they will throw an `IllegalArgumentException` rather than an `IndexOutOfBoundsException` for negative values.
> 
> The PR also proposes to fix a bug where the allocation size would overflow and the specified exception was not thrown.
