I get this message on every call of DrawElements, although I do not map a single buffer throughout the course of the program. The code (not a testcase, but small program) is located here
(depends on CMake, GLFW, Version overrides 3.3/330)
The message is caused by iod/planet.c:660.
RadeonHD 4890 does not emit any such warning.

Yeah, it's coming from perf_debug() in i965, which is supposed to alert application developers to performance problems in their applications.
Your application has now changed significantly since this was filed, so I can't even be sure there's still a problem.
I tried to run your program, but it asserts, presumably not able to find the shaders. Unclear to me how I'm supposed to run it.
Practically it might not be a problem, but I assume it may become one at any time again. In order for it to find the shaders, you have to `make install`:
cmake -D CMAKE_INSTALL_PREFIX=../install ..
