Sven van Haastregt 9772516c3f cmake: Enable -Wall for non-release builds (#1686) ...

Enable a larger set of compiler warnings globally for gcc/clang-like
compilers.  This should help catch issues early and result in better
code quality.  These warnings are primarily aimed at OpenCL-CTS
developers, so only enable them for non-release builds.

Ensure `-Wall` and `-Werror` are set before any `-Wno-...` options, as
the `-Wall`/`-Werror` flags undo `-Wno-...` for some compilers.

The code base does not compile cleanly with `-Wall` yet, so disable
some warnings.  Do this globally for now, to keep this patch small and
localized.

Silence `-Wunknown-pragmas` (instead of only making them non-fatal),
to avoid verbose warning logs.
