jhb 5c30edda81 Implement 32-bit atomic_fcmpset() in userland for armv4/v5. 
- Add an implementation of atomic_fcmpset_32() using RAS for armv4/v5.
  This fixes recent world breakage due to use of atomic_fcmpset() in
  userland.
- While here, be more careful to not expose wrapper macros for 64-bit
  atomic_*cmpset to userland for armv4/v5 as only 32-bit cmpset is
  implemented.

This has been reviewed, but not runtime-tested, but should fix the arm.arm
and arm.armeb worlds that have been broken for a while.
