[c++17] Visit class template explicit specializations just like all other class definitions in codegen.
...
If an explicit specialization has a static data member, it may be a definition and we may need to register it for emission.

For better compatibility with C++11 and C++14, emit a nondiscardable definition
...
of a static constexpr data member if it's defined 'constexpr' out of line, not
only if it's defined 'constexpr' in the class.

PR28394: For compatibility with c++11 and c++14, if a static constexpr data
...
member is redundantly redeclared outside the class definition in code built in
c++17 mode, ensure we emit a non-discardable definition of the data member for
c++11 and c++14 compilations to use.

Implement C++17 P0386R2, inline variables. (The 'inline' specifier gives a
...
variable weak discardable linkage and partially-ordered initialization, and is
implied for constexpr static data members.)
