event_map_lookup: when looking for a previous access to an address,
find conflicting accesses that overlap the current access in any way,
rather than just match at the addresses. This allows reporting of
conflicts between accesses which overlap but are not the same
size/alignment.
Doesn't seem to always work reliably, for reasons I don't understand,
but I so far failed to make a small test case.
