cmake: adjustments for inside ROOT buildsystem

inside ROOT Vc_INSIDE_ROOT is defined. In that case we need to do some
adjustments for nameing and placing the tests.
Also the libc++ switch is now left alone - the ROOT buildsystem needs to
figure it out.

cmake: disable warning C4290 with MSVC

that warning is useless noise. I don't care whether MSVC would have done
what I wanted without this statement. This statement is required by the
C++ standard, so please don't warn about it.

The switch is in CMakeLists.txt instead of VcMacros.cmake because it's
only needed for unittest.h.

cmake: add build_tests target

I added a new custom target 'build_tests' that has all test executables
as dependency. In development versions build_tests is made with all, in
release versions you'll have to make build_tests explicitly. A standard
make all will then only build libVc.

docs: don't generate LaTeX and man

The latex output from doxygen is broken (missing namespaces.tex) and the
man output looks too unreadable to be useful. So I'd rather only keep
the HTML variant for now. Until somebody wants to maintain one of these
other outputs.

The .qhp file is an intermediate file that can be removed after the .qch
file is created.

ctest: support ctest runs Debug

CMAKE_BUILD_TYPE was "hardcoded" to Release. Now the build_type
environment variable can overwrite this default. Also this string is now
added to the BUILD_NAME.

workaround GCC not recognizing sizeof as immediate

GCC builtins that require an immediate don't compile with sizeof as
argument unless -O2 is given. This workaround assigns the value of the
sizeof operator to an enum and uses the enum as parameter to the
builtin.
