[Ada] Fix bugs in Value_Size clauses and refactor
gcc/ada/
* sem_ch13.adb (Analyze_Attribute_Definition_Clause): Combine
processing of Size and Value_Size clauses. Ensure that
Value_Size is treated the same as Size, in the cases where both
are allowed (i.e. the prefix denotes a first subtype). Misc
cleanup.
* einfo-utils.adb (Init_Size): Add assertions.
(Size_Clause): Return a Value_Size clause if present, instead of
just looking for a Size clause.
* einfo.ads (Has_Size_Clause, Size_Clause): Change documentation
to include Value_Size.
* sem_ch13.ads, layout.ads, layout.adb: Comment modifications.
