pack partial_symtab for space
This improves the packing of struct partial_symtab. I noticed with
pahole that were were a couple of holes. This consolidates the holes
without, I think, affecting readability -- it just moves the "user"
field a bit earlier in the struct. This change saves a small amount
of memory.

* psympriv.h (struct partial_symtab) <user>: Move earlier.
