Subject: [Ada] Gnatfind crash on references to unknown files
Authentication-results: sourceware.org; auth=none

This patch fixes an obscure bug in gnatfind that could cause it to
crash on references to unknown files. The crash was caused by
dereferencing an uninitialized pointer value, so it was flaky.
No test is available.

Tested on x86_64-pc-linux-gnu, committed on trunk

	* xref_lib.adb (Parse_X_Filename, Parse_Identifier_Info): Ignore
	unknown files. Check that File_Nr is in the range of files we
	know about. The previous code was checking the lower bound,
	but not the upper bound.
