Update NEWS with some core and platform (s390) changes and bug fixes.

Mention the new DWARF version 5 support needed with GCC 11.
s390 now supports z14 vector instructions.
Add missing bugs fixed and sort them by bug number (n-i-bz last).
Pull in 3.16.1 release data.

 * ==================== CORE CHANGES ===================
 
+* DWARF version 5 support
+
+  - Valgrind can now read DWARF version 5 debuginfo as produced by GCC 11
+
+* ================== PLATFORM CHANGES =================
+
+* s390:
+
+  - Implement the new instructions/features that were added to
+    z/Architecture with the vector-enhancements facility 1.  Also
+    cover the instructions from the vector-packed-decimal facility
+    that are defined outside the chapter "Vector Decimal
+    Instructions", but not the ones from that chapter itself.
+
+    For a detailed list of newly supported instructions see the
+    updates to `docs/internals/s390-opcodes.csv'.
+
+    Since the miscellaneous instruction extensions facility 2 was
+    already added in Valgrind 3.16.0, this completes the support
+    necessary to run general programs built with `--march=z14' under
+    Valgrind.  The vector-packed-decimal facility is currently not
+    exploited by the standard toolchain and libraries.
