adaace8aa8 Set isBarrier = 1 on return instructions, as they are control barriers.

533297b58d Rename usesCustomDAGSchedInserter to usesCustomInserter, and update a
bunch of associated comments, because it doesn't have anything to do
with DAGs or scheduling. This is another step in decoupling MachineInstr
emitting from scheduling.

xs1a and xs1b.

early development boards which is no longer supported in the
XMOS toolchain.

29cab5f0ee Add pseudo instructions to the XCore for (load|store|load address) of a
frame index. eliminateFrameIndex will replace these instructions with
(LDWSP|STWSP|LDAWSP) or (LDW|STW|LDAWF) if a frame pointer is in use.

This fixes PR 3324. Previously we used LDWSP, STWSP, LDAWSP before frame
pointer elimination. However since they were marked as implicitly using
SP they could not be rematerialised.
