commit.h: rearrange 'index' to shrink struct commit
On linux 64-bit architecture, pahole finds that there's a 4 bytes padding after 'index'. Moving it to the end reduces this struct's size from 72 to 64 bytes (because of another 4 bytes padding after graph_pos). On linux 32-bit, the struct size remains 52 bytes like before.
