ec: Add macro to check if constant index is too large
BUILD_ASSERT can only be used for declarative code, add a macro to check
if a condition resolved at build time is true or not.
Take advantage of compiler detection of division by zero error message.
[-Werror=div-by-zero]
BUG=none
BRANCH=eve,nocturne
TEST=compile, check error is detected when condition is not true.
