Reduce code size by avoiding static inline member variables

Static inline member variables require the compiler to emit a static
runtime constructor in all translation units that can see the variables
in question. This normally wouldn't be a problem, but it gets expensive
really quickly when you have ~3000 classes and ~3000 duplicate
static constructors.

This drops the ELF size from ~270MB to ~220MB and probably speeds up
builds a little bit.
