Suppress more variable-set-but-not-used warnings from clang 15.
Mop up assorted set-but-not-used warnings in the back branches. This includes back-patching relevant fixes from commit 152c9f7b8 the rest of the way, but there are also several cases that did not appear in HEAD. Some of those we'd fixed in a retail way but not back-patched, and others I think just got rewritten out of existence during nearby refactoring. While here, also back-patch b1980f6d0 (PL/Tcl: Fix compiler warnings with Tcl 8.6) into 9.2, so that that branch compiles warning-free with modern Tcl. Per project policy, this is a candidate for back-patching into out-of-support branches: it suppresses annoying compiler warnings but changes no behavior. Hence, back-patch all the way to 9.2.
