Fix assertion failure on VSS library
gcc/ada/
PR ada/108858
* sem_ch6.adb (Analyze_Subprogram_Body_Helper): For functions with
separate spec, if their return type was visible through a limited-
with context clause, their extra formals were not added when the
spec was analyzed. Now the full view must be available, and the
extra formals can be created and Returns_By_Ref computed.
