Julius Werner b8534f767c assert: Add new dead_code() macro to assert dead code paths 
This patch adds a new kind of compile-time assertion based on Linux'
compiletime_assert(). The difference to the existing use of
_Static_assert() in coreboot (which should continue to be used where
appropriate) is that this new assertion only hits if the call to it is
not optimized out at compile time. It is therefore ideal to assert that
certain code paths are not included in the image if a certain Kconfig
option is (not) set. For example,

 assert(!IS_ENABLED(CONFIG_THAT_MAKES_THIS_INAPPROPRIATE));

can be rewritten as

 if (!IS_ENABLED(CONFIG_THAT_MAKES_THIS_INAPPROPRIATE))
   dead_code("This code shouldn't be built for config X");

to turn it into a compile-time check.
