Some improvements, like making it simple to actually remove a statement
or a token including its associated whitespace.

The warn_unused attribute has been upstream to GCC and Clang, so use it if present.
Still warn about STL types if those do not use it yet (which is the status as of now).

C/C++ silently converts pointers to booleans, which is presumably seen as
a good idea by lazy people, but it can occassionally silently break code
in strange ways, most notably by selecting a bool overload when no matching
overload for the pointer exists (OUStringBuffer::append() can break like that,
e.g. in ba37e4062f538db7e51d6a64ba544eeddbc567cf, other cases are
8e3bf1598fa95ac8d099e45ae4252e7654a6f590 or 28e4c0250e67a344b4d6088bdca2e680a4bffad0).
So far the plugin checks only conversions in function call arguments, there's
disabled code that could check more places, but I'm not aware so far of any place
where anything actually broke because of that, and it'd require fixups to be
explicit in some places (e.g. 'bool b = returns_pointer();' would require '!= NULL'
added), so for it'll be only the simple various and it can be made more strict if wanted.

Ctor bodies can also have code inside of member variables initialization,
which is not considered to be inside function body.

Clang API doesn't provide this, but it's occasionally needed, and so far
the way has been inspecting the highest possible node in AST and walking down
and remembering, which is complicated, error-prone and annoying.

A different way to do 1c0669af2f1f58e6431b5e489ac48a883e242ba7.
Sometimes one piece of code can be represented several times in the AST,
e.g. with default function arguments.

This does not always work well, e.g. when building a return value
in a return statement from a temporary, there is CXXConstructExpr
containing CXXTemporaryObjectExpr, which both share the same location.
This reverts commit 1c0669af2f1f58e6431b5e489ac48a883e242ba7.
Turns out removeText( SourceRange ) treats it as a token range, so it's
not always character-exact if used for removal of only several characters
from a token (e.g. an identifier).

It's possible to get the latter from the former, and the former
is useful for other things too (access to the preprocessor, for example).

So running the compiler plugin can be done either with FORCE_COMPILE_ALL=1
for simplicity, running the plugin on all source files for the target,
or it's possible to use make's -W option (or touch files manually) to
run it only for selected files.
