Excellent. Just one comment on the updated patch. It seems fine otherwise:

+    unsigned Opc2 = Is64Bit ? AArch64::FMOVXDr : AArch64::FMOVWSr;
+    unsigned ResultReg = createResultReg(TLI.getRegClassFor(VT));
+    BuildMI(*FuncInfo.MBB, FuncInfo.InsertPt, DbgLoc, TII.get(Opc2), ResultReg)
+        .addReg(TmpReg, getKillRegState(true));

This bit of FastISel can just emit a generic COPY node, it'll be
handled by copyPhysReg, and might even be elided in some slightly
weird situations.

Cheers.

Tim.
