Based on discussion so far I am inclined to
- make the default build type RelWithDebInfo
- udpate cpp/INSTALL discussion of build types (it does mention
Release/Debug already, I'll add mention of the other types.

We don't have unanimity over Release vs. RelWithDebInfo as the preferred
default, but RelWithDebInfo appears to have more support. Don't forget
this is only the default, people can choose whatever they prefer (and
the INSTALL will be updated so they'll know what the choices are)
