* Allow overlap of bit-field storage units
Previously,
struct s {

unsigned int y : 10;

had sizeof(struct s) == 4.
With this change, allow the storage units of x and y to overlap,
so sizeof(struct s) == 3, with y stored immediately after x,
with no padding between them.
An int bit-field (the only type currently supported) will still
never occupy more than two bytes.
