RFR: 8305201: Improve error message for GroupLayouts that are too large on SysV [v2]

[Jorn Vernee]

> Using for instance a struct layout that contains an unbounded array will produce the exception from the JBS issue.
> 
> This patch checks for the case where a GroupLayout is too large more explicitly, and reports the issue using a more informative exception.
