Apple has kept their 64-bit plans secret until recently, but now they want as many apps as possible to migrate to 64-bit. That may mean a big push for 64-bit support in LLVM, which can be built upon by GHC...

Also, the iPhone 5S is the first with 64-bit support, and for best
performance all apps should be 64-bit (because then no 32-bit libs need
to be loaded, and there are more general purpose and floating point
registers in 64-bit mode). Are there any roadblocks preventing the
creation of 64-bit GHC/iOS7 apps?

Yes, it is "just" one: GHC's ARMv8 support is completely missing.
