Improved the BUILD_ASSERT macro to work outside of functions.
This will let us check the size of static array initializers.
Also moved this macro definition and ARRAY_SIZE into a new "tricks.h"
header, so that userspace utils can use it too.
BUG=none
BRANCH=none
TEST=manual
Built everything, tested on Link. Tried various assertions.
