Enabling the extra warnings also enabled some additional clang-only warnings, as a result building i915 with clang currently is extremely noisy. For now also disable the clang warnings sign-compare, sometimes-uninitialized, unneeded-internal-declaration and initializer-overrides. If desired they can be re-enabled after the code has been fixed.
