While we reshuffle the presence members, move the counts as well.
Previously array count members would have been place directly in
the struct, so:
struct family_op_req {
struct {
u32 a:1;
u32 b:1;
} _present;
struct {
u32 bin;
} _len;
u32 a;
u64 b;
const unsigned char *bin;
u32 n_multi; << count
u32 *multi; << objects
};
Since len has been moved to its own presence struct move the count
as well:
struct family_op_req {
struct {
u32 a:1;
u32 b:1;
} _present;
struct {
u32 bin;
} _len;
struct {
u32 multi; << count
} _count;
u32 a;
u64 b;
const unsigned char *bin;
u32 *multi; << objects
};
This improves the consistency and allows us to remove some hacks
in the codegen. Unlike for len there is no known name collision
with the existing scheme.
