It will simplify creating RL-VLCs (which until now used
a stack-based VLC as temporary buffer).
Notice that there would be another option to merge them, namely:
struct VLCElem {
union {
VLCBaseType sym;
int16_t level;
};
int8_t len;
uint8_t run;
};
The main difference to the current patch is that this would change
the type of the length field of VLCElem to int8_t from int16_t.
It turns out that that this would entail additional sign extensions
on ppc, see https://godbolt.org/z/behWYEYE7. I have therefore refrained
from doing so, although it would make the patch simpler.
