_mul_overflow and get_encoded_value
A sufficiently mad compiler optimiser can take undefined behaviour
according to the C standard as an opportunity to remove code. Since
"data + size" might be seen to be past the end of an array,
calculating such an expression is UB.
_mul_overflow is infrastructure for later patches.
* bucomm.h (_mul_overflow): Define.
* dwarf.c (get_encoded_value): Avoid pointer UB.
