Tim Northover d29bae8bc9 AArch64: enable MISched by default.
Substantial SelectionDAG scheduling is going away soon, and is
interfering with Hao's attempts to implement LDn/STn instructions, so
I say we make the leap first.

There were a few reorderings (inevitably) which broke some tests. I
tried to replace them with CHECK-DAG variants mostly, but some too
complex for that to be useful and I just reordered them.
