This fully deprecates all uses of the RUNTIME_ASSERT macro and removes
the macro and underlying logging function in question. All uses have
been replaces with CHECK macros which crash safely even in production.

It makes sure we discover abuse of runtime functions in the wild early
and also abort the process safely. Breaking assumptions in any runtime
function can no longer accidentally be caught by JavaScript.
