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

Tue Dec 12 10:09:45 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.
