Pre-C++14 compilers

Recently we stopped supporting C++03. Now, the only compilers which
support C++11, but do not claim some support of C++14 (that I am aware
of) are GCC versions 4.8 and 4.9. But even C++11 support in those GCC
versions is fairly buggy and those who still test on them often have
to resort to various tricks to make their code build. Those compilers
are fairly old, and the systems that use them increasingly go extinct.
This makes me consider removing them from CI. Which is why I want to
ask the community several questions:

1) Do you still use GCC 4.8 or 4.9?
2) If you do, is there a specific date when you plan to drop them?
2) Do you use some other compiler which supports C++11, but not C++14
(even with flags like -std=c++1y)?
