Ada: Remove debug line number for DECL_IGNORED_P functions
It was pointed out in PR101598 to be inappropriate, that
ignored Ada decls receive the source line number which was
recorded in the function decl's DECL_SOURCE_LOCATION.
Therefore set all front-end-generated Ada decls with
DECL_IGNORED_P to UNKNOWN_LOCATION.
