17569fe05b Some additional tests for Thumb atomic load and store (which I somehow forgot to commit earlier).

981a010c09 Relax the MemOperands on atomics a bit. Fixes -verify-machineinstrs failures for atomic laod/store on ARM.
(The fix for the related failures on x86 is going to be nastier because we actually need Acquire memoperands attached to the atomic load instrs, etc.)

4136d23c48 Don't fast-isel for atomic load/store; some cases require extra handling missing from fast-isel.

069e2ed794 Atomic load/store on ARM/Thumb.
I don't really like the patterns, but I'm having trouble coming up with a
better way to handle them.

I plan on making other targets use the same legalization
ARM-without-memory-barriers is using... it's not especially efficient, but
if anyone cares, it's not that hard to fix for a given target if there's
some better lowering.
