hopefully make it possible to remove the annoying initial :: when
referring to the global tools namespace. Unless we have even more
tools subnamespaces somewhere.
Thorsten said it was OK.

written with an elaborated type keyword, but also when it is written with a
qualified name).
(I originally wrote testArithmeticTypedefs to track down a different issue,
which turned out to be a non-issue, with this fix as fall-out. So that test
doesn't quite match the theme of this commit, but is a worthwhile addition
nonetheless.)

...motivated by <https://gerrit.libreoffice.org/#/c/41565/2> adding dead code
at the end of a switch statement, after the last case's "break".
-Wunreachable-code appears to work well on Clang, while it appears to have no
effect on GCC.
Most of the affected places are apparently temporary/TODO/FIXME cases of
disabling code via "if (false)", which can be written with an extra set of
parentheses as "if ((false))" to silence -Wunreachable-code on Clang (which thus
needed loplugin:unnecessaryparen to be adapted accordingly). In some cases,
the controlling expression was more complex than just "false" and needed to be
rewritten by taking it out of the if statement to silence Clang.
One noteworthy case where the nature of the disabled code wasn't immediately
apparent:
Sep 12 16:59:58 <sberg> quikee, is that "if (false)" in
ScExponentialSmoothingDialog::ApplyOutput
(sc/source/ui/StatisticsDialogs/ExponentialSmoothingDialog.cxx) some work-in-
progress or dead code?
Sep 12 17:02:03 <quikee> sberg: WIP, but you can remove it
Sep 12 17:04:47 <sberg> quikee, I'll wrap the false in an extra set of
parentheses for now, to silence -Wunreachable-code (I wouldn't want to
remove it, as I have no idea whether I should then also remove the "Initial
value" comment preceding it)
Sep 12 17:07:29 <quikee> sberg: both are different ways to calculate the
"intital value"... so no
Another case where the nature of the dead code, following while (true) loops
without breaks, is unclear is sd/source/ui/remotecontrol/BluetoothServer.cxx,
where I added TODO markers to the workarounds that silence the warnings for now.
basic/source/sbx/sbxvalue.cxx had a variable of type double, of automatic
storage duration, and without an initalizer at the top of a switch statement.
Clang warning about it is arguably a false positive.
Apart from that, this didn't find any cases of genuinely dead code in the
existing code base.

...to find uses of dynamic_cast where the static (base) type has hidden
visibility while the dynamic (derived) one has default visibility, and which may
thus fail at least on macOS like happened in
d5ed3cd6dbd22bb18542778f1c48f4d5b3ae0f95 "Make WinMtfFontStyle's base class
EMFIO_DLLPUBLIC, too".
libcxxabi's __dynamic_cast takes static_type and dst_type arguments. Now, if
dst_type (the derived type, with default visibility) is taken from .so A (and
thus references the version of the base type info hidden in .so A) but the
__dynamic_cast call is made from .so B, it passes for static_type the base type
information hidden in .so B, and __dynamic_cast will consider the cast to fail.
I'm not sure whether hidden intermediary types (in the hierarchy between the
dynamic_cast's base and derived types) acutally cause a problem too, but lets
flag them with the plugin anyway.
The fixes use SAL_DLLPUBLIC_RTTI. For one, there appear to be no other reasons
than type visibility to make those classes SAL_DLLPUBLIC. For another, this
nicely avoids any actual changes on Windows (where SAL_DLLPUBLIC expands to
nothing, and many of the affected classes were explicityl introduced into class
hierarchies as "MSVC hacks").

But turns out this whole avoidance is ill-advised and should eventually be
reverted:
Aug 31 09:09:26 <sberg> noelgrandin, the way you originally handled CastExpr in
constparam's checkIfCanBeConst, your intent was if there's code like
static_cast<T*>(p) and param p is found it can be made const, one would also
need to change that cast to static_cast<T const *>(p) when fixing the loplugin
warning, right?

ScJumpMatrix has no copy constructor, so I just managed it via
