Bump minimum GCC version and note impending VS2015 deprecation.

GCC 6.1 was released more than five years ago, April 27, 2016. We can
thus drop some bits in the CMake files.

https://gcc.gnu.org/develop.html#num_scheme

Also note in BUILDING.md that VS2015 will no longer be supported next
year. Then we can cycle our CQ to testing VS2017 + VS2019. (We're
currently not testing VS2019 at all, though so far it hasn't been an
issue.) I've been running into some VS2015-only C++ issues around
conversions, so once we stop testing it, I expect it'll break.
