Fix loplugin:simplifypointertobool for libstdc++ std::shared_ptr

...where the get member function is defined on a std::__shared_ptr base class,
so loplugin:simplifypointertobool used to miss those until now.  (While e.g.
using libc++ on macOS found those cases.)

366d08f2f6d4de922f6099c62bb81b49d89e0a68 "new loplugin:simplifypointertobool"
was mistaken in breaking isSmartPointerType(const clang::Type* t) out of
isSmartPointerType(const Expr* e); c874294ad9fb178df47c66875bfbdec466e39763 "Fix
detection of std::unique_ptr/shared_ptr in loplugin:redundantpointerops" had
introduced that indivisible two-step algorithm on purpose.

The amount of additional hits (on Linux) apparently asked for turning
loplugin:simplifypointertobool into a rewriting plugin.  Which in turn showed
that the naive adivce to just "drop the get()" is not sufficient in places that
are not contextually converted to bool, as those places need to be wrapped in a
bool(...) functional cast now.  If the expression was already wrapped in
parentheses, those could be reused as part of the functional cast, but
implementing that showed that such cases are not yet found at all by the
existing loplugin:simplifypointertobool.  Lets leave that TODO for another
commit.

Besides the changes to compilerplugins/ itself, this change has been generated
fully automatically with the rewriting plugin on Linux.
