This was already the case for plain addresses, but it was not being
considered in the case of an arithmetic operation.

The check was not being applied on certain conditions.

This way instructions which might make use of bare memory numbers can
freely ignore the address sanitizer when it actually makes sense.

The address sanitizer is now able to detect whenever in an instruction a
memory access is done without using variables. This is now detected for
all instructions except for branching, which falls outside of this
scope.
Moreover, simple arithmetics is allowed and bounds are checked for
simple cases. That being said, more involved bound checks should be done
with other tools (e.g. emulators).
