Original commit message:
Also add backend flags that tell whether integer division/modulus is
generally safe, i.e. does not trap on overflow or divide by zero.

These operators are not supported by any backends yet, and a backend is free to not support them.

Original commit message:
This is required to fix a tricky branch fusion bug on ARM, which was
caused by the interaction between the architecture-independent and
architecture-specific parts of the InstructionSelector. In the end it
wasn't worth sharing a few common lines of code for the additional
complexity, especially if we also want to properly support architectures
without any dedicated flags register (i.e. MIPS).
