LOG: [memprof] Disable pedantic warnings, suppress variadic macro warning.

The memprof unit tests use an older version of gmock (included in the
repo) which does not build cleanly with -pedantic:
https://github.com/google/googletest/issues/2650
For now just silence the warning by disabling pedantic and add the
appropriate flags for gcc and clang.
