After a syntax error, if the code is compiled with -gnatq, semantic
analysis should still proceed without internal errors if possible. Add
special case to recognize ill-formed array type.
Tested on x86_64-pc-linux-gnu, committed on trunk
gcc/ada/
* layout.adb (Layout_Type): Do not call Number_Dimensions if the
type does not have First_Index set.
