[Ada] No Storage_Error for an oversized disabled ghost array object
In some cases where the size computation for an object declaration will
unconditionally overflow, the FE generates code to raise Storage_Error
at the point of the object declaration (and may generate an associated
warning). Don't do this if the object declaration is an ignored (i.e.,
disabled) ghost declaration.

gcc/ada/
* freeze.adb (Freeze_Object_Declaration): Do not call
Check_Large_Modular_Array when the object declaration being
frozen is an ignored ghost entity.
gcc/testsuite/
* gnat.dg/ghost7.adb, gnat.dg/ghost7.ads: New testcase.
