In GCC, insns are represented algebraically, so portable optimizations
are easy to implement.  GAS does not use such representations.  So
putting scheduling in GAS would require adding entirely new layers of
hair, which would slow it down greatly.  This is a big reason to put
scheduling in GCC, not in GAS.
