Subject: [NFC] hash constant string as void* (#6863)

possible-contents.h hashes the location for caught exnrefs by hashing an
arbitrary string, "caught-exnref-location". It previously used
`std::hash<const char*>` for this, but some standard library
implementations report an error when this template instantiation is used
because hashing the location of a string is almost never correct. In
this case it is fine, so switch to using `std::hash<const void*>`.
