Subject: ALL: Remove obsolete register keyword

The register keyword was deprecated from the C++11 standard,
<http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2014/n4193.html#809>,
and removed from the C++17 standard,
<http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2015/n4340>, so
cannot exist in a well-formed C++17 program.

It has never done anything in GCC
<https://gcc.gnu.org/ml/gcc/2010-05/msg00113.html>
and because of the way it is specified in the standard, it is “as
meaningful as whitespace”
<http://www.drdobbs.com/keywords-that-arent-or-comments-by-anoth/184403859>.

The one remaining use of the register keyword is in the DS backend,
where it is used to create a local register variable using the
non-standard GCC Extended Asm feature.

Closes gh-1079.
