[Ada] Fix bogus error on array with overaligned scalar component

The compiler would wrongly reject an alignment clause larger than 8 on
the component type of an array of scalars, which is valid albeit
pathological.

gcc/ada/

* layout.adb (Layout_Type): Do not set the component size of an
array with a scalar component if the component type is
overaligned.

gcc/testsuite/

* gnat.dg/alignment14.adb: New testcase.
