Description

We have a number of unit tests that need to exercise code paths where memory in excess of 2-4GB is allocated. Some of these are marked as DISABLED_* in googletest which seems to be a recipe for bitrot.

I propose instead to have a CMake option that sets a compiler definition to enable these tests at build time, so that they can be run regularly on machines that have adequate RAM (i.e. not public CI services)
