build system: use version number comparison for -Wshadow-compatible-local test
...
clang++ doesn't error out on unknown flags, it only spews
warnings. Therefore AC_TRY_COMPILE is useless for detecting support
for it.

configure: get real version for clang(++)
...
`clang++ -dumpversion` always outputs 4.2.1 as it was designed to be
compatible with `g++` in that version. So parse `clang++ --version`
for `clang++` instead.

build system: check for and turn off some new warnings from clang++ 3.6
...
These warnings include -Winconsistent-missing-override and
-Wpotentially-evaluated-expression which are both triggered by code out
of my control (Qt and wxWidgets).
