Each plugin currently uses its own recursive AST run, which adds up.
This patch adds another shared plugin which internally contains all
(suitable) plugins and dispatches to them from the same one recursive
run. This patch converts ~25 plugins and for starmath's accessibility.cxx
reduces clang build time from 5.43s to 5.14s (and it's 4.39s without any
plugins). As there are almost 50 more plugins to go, this can theoretically
result in 4.56s final time, although probably not all plugins can be
that easily converted, if at all.
This mostly requires very little change in many plugins (see e.g.
BadStatics), some even work without any functionality change (e.g.
CharRightShift). Traverse* calls require some changes but are often
not that difficult. WalkUp* probably can't be supported, although some
plugins can(?) possibly be adjusted to not rely on them. And of course
some plugins can be left as they are, using their own recursive run.
See description at the top of generator.cxx for description of how to
convert a plugin.
The sharedvisitor.cxx source is generated based on scanning relevant
plugin sources using a clang-based scanner/generator. The generated
source is intentionally included instead of getting always generated,
as the generating currently takes some time, so it should get updated
in git whenever a change in a plugin triggers a source change in it.

There are some problems here, this should fix one of them: the
getFilename function returns "<stdin>" for spelling locations, because
the input to clang is sort of preprocessed via -frewrite-includes if
icecream is used and the file is built on a remote host (whereas it's
apparently not preprocessed if the file is compiled locally by icecream).
Using getPresumedLoc() uses the #line directives in the preprocessed
input, which avoids the problem but is more expensive, so try to use it
only when necessary.
The getFileEntry(getMainFileID())->getName() pattern will also result
in "<stdin>", but fortunately icecream passes -main-file-name,
which oddly enough isn't used by the SourceManager's spelling locations,
but is available separately via CodeGenOptions.
This builds everything successfully with clang version 6.0.0:
ICECC_PREFERRED_HOST=myremote make check gb_SUPPRESS_TESTS=t

This reverts commit b39e627be4. The assumed (see
comment at <https://gerrit.libreoffice.org/#/c/46769/4/compilerplugins/clang/
plugin.cxx@633>) performance bottleneck of isSamePathname -> getAbsolutePath
does show up in Flamegraph inspections of LO builds. But changing (non-member
function) isSamePathname to only call getAbsolutePath if (PluginHandlder member
function) isLOOLMode is true would need some code reorg, and Online development
doesn't seem to make too much actual use of the plugin, so conclusion on IRC was
to revert.

...to enable debug-only code in the plugins. Some situations in the plugin code
should never happen, yet must not by default report errors or trigger
assertions, as some newly written LO code could trigger them nevertheless (in
which case the plugin code will likely need to be adapted, to cater for these
presumed-impossible situations).
Such code can now be included in the plugins behind an if(isDebugMode()) guard,
and can explicitly be enabled with --enable-compiler-plugins=debug.
I deliberately made this a runtime rather than a compile time option (using
some #ifdef guards in the plugin code, say), as it IMO keeps the code more
readable, and also allows overridding COMPILER_PLUGINS_DEBUG=... on the make
command line.

...which is there for MSVC compatibility, but can cause getBody() to return null

And in staticmethods.cxx we need to check doesThisDeclarationHaveABody() instead
of hasBody(): For some class template member functions that are only defined
outside their class definition, as is the case for
OSequenceIterator::hasMoreElements in include/comphelper/sequence.hxx, hasBody()
may be true for the original member function declaration inside the class (as
there is some later definition that does have a body), but
isLateTemplateParsed() is not (it is only true for the later definition). So
just skip any such declarations that are not definitions (which is sane anyway,
as otherwise such functions could pointlessly be inspected multiple times).
