this fixes an issue where a lua library function triggers an exception after it does a math operation which changes the floating point registers on M7 MCUs (such as STM32H7). An example is math.random() which calls math_random(), which pre-calculates a double value before checking if the arguments to the call are valid. When it then checks and finds invalid values the exception longjmp does not restore the floating point registers.
