Emit user subtypes with -fgnat-encodings=minimal
This changes the compiler to emit debug info for user-defined subtypes
with -fgnat-encodings=minimal, as they might be needed by the debugger.
gcc/ada/ChangeLog:
* gcc-interface/decl.c (gnat_to_gnu_entity) <E_Record_Subtype>: Set
debug type to the base type and only if the subtype is artificial.
