[Ada] Fix internal error on extension of record with representation clause
This fixes a long-standing issue present for extensions of tagged record
types with a representation clause: the clause is correctly inherited
for components inherited in the extension but the position and size are
not, which fools the logic of Is_Possibly_Unaligned_Object.
This can result in an attempt to take the address of a component not
aligned on a byte boundary, which is then flagged as an internal error.

gcc/ada/
* exp_util.adb (Is_Possibly_Unaligned_Object): For the case of a
selected component inherited in a record extension and subject
to a representation clause, retrieve the position and size from
the original record component.
gcc/testsuite/
* gnat.dg/rep_clause7.adb: New testcase.
