...in templated code, to cater for the needs of
<https://gerrit.libreoffice.org/c/core/+/124400> "Prepare for removal of
non-const operator[] from Sequence in testtools".
For one, by defining ImplicitBoolConversion::TraverseInitListExpr, make sure
that Clang versions before and after
<0a42fe70a5>
"[AST] Treat semantic form of InitListExpr as implicit code in traversals"
behave the same. Old versions of Clang would have erroneously reported
Sequence<Sequence<sal_Bool>> s2{ { false } };
(and reported
Sequence<Sequence<sal_Int32>> s4{ { false } };
twice) in compilerplugins/clang/test/implicitboolconversion.cxx when one of the
four combinations of syntactic/semantic visit of the outer/inner InitListExpr
defeated the intended suppression logic in
ImplicitBoolConversion::TraverseCXXStdInitializerListExpr.
And for another, ImplicitBoolConversion::TraverseInitListExpr can subsume the
exising ImplicitBoolConversion::TraverseCXXStdInitializerListExpr.
But for a third, that would still make
Sequence<Wrap2<sal_Bool>> s6{ { false } };
in compilerplugins/clang/test/implicitboolconversion.cxx emit a false warning,
so add a cheesy "TODO" chicken-out special case to
ImplicitBoolConversion::checkCXXConstructExpr for now.
