Fix lua failure to catch divide by zero and NaN exceptions

I can only assume in the course of the original conversion to fixed point
math in RbLua the fact that division by zero and NaN handling was to be
caught as a graceful exception by the floating point handler was overlooked.

As a result lua doesn't handle these exceptions and instead results in a
panic on the device.

This patch fixes this handling in the lexer for compile time Inf and Nan
results and in the luavm for runtime division by zero (Inf)

I missed the runtime exception of n%0 added checks for that as well..
