Message:

Remove uses of warnings to show test success. Eliminate simple causes of other warnings from affected tests and remove the result from WFLAG_OPT_LAX.

Many affected tests also formerly used -fsyntax-only to avoid errors at later compilation stages, or at runtime. Repair such tests to actually work though runtime, and remove them from SYNTAX_ONLY_CODE.

Group tests listed under WFLAGS_OPT according to why they should receive lax treatment. Add reason WFLGAS_OPT_LAX_EXPECT_WARN and give the original list reason WFLGAS_OPT_LAX_TO_INVESTIGATE.

Tests whose purpose is to show a warning are listed as both SYNTAX_ONLY_CODE (so that the warning is the output) and WFLGAS_OPT_LAX_EXPECT_WARN (to document this fact).
