Bring back r250262: PS4 toolchain
There was a minor problem with a test. Sorry for the noise yesterday.
This patch adds missing pieces to clang, including the PS4 toolchain
definition, added warnings, PS4 defaults, and Driver changes needed for
our compiler.
A patch by Filipe Cabecinhas, Pierre Gousseau and Katya Romanova!
