From-SVN: r260741

This patch modifies the expansion of default-initialized array objects when
pragma Initialize_Scalars or Normalize_Scalars is in effect to suppress the
generation of checks on the constructed in-place aggregate. The aggregate
intentionally contains invalid values which may not necessarily fit the
constraints of a particular component type. Check suppression ensures that
no spurious checks are generated, and that the effects of the pragmas are
carried out.
