src/include/assert.h: add noreturn attribute to dead_code()
Clang does not recognize dead_code() as termination of execution. It
gives this message:
error: control reaches end of non-void function
[-Werror,-Wreturn-type]
This change adds an __attribute__((noreturn)) to ensure that clang
recognises that this function will terminate execution.
This change is more general solution to the problem that was addressed
in the specific at https://review.coreboot.org/c/coreboot/+/32798
