Hi!
Here it is in patch form, at the same time I've turned it into bit-fields.
On x86_64-linux, this reduced .rodata by 532 bytes (so 5.75x reduction
of the variable) and grew the cpp_set_lang function by 26 bytes (8.4%
growth).
So far smoke tested, ok for trunk if it passes full bootstrap/regtest?
