Benedikt Meurer 05627e0de4 Merge the new ARM backend into trunk (PR#5433). 
Initial merge of the new ARM backend (commit ec5b444c7f) from my development
repository at https://github.com/bmeurer/ocaml-arm/tree/ec5b444c7f .

Compared to the old ARM backend, this one does the following:
- Support for both software and hardware floating-point (VFPv3).
- Properly supports interworking with Thumb/Thumb-2 code for both OCaml and C
  code.
- Supports dynamic linking and large memory models (PR#5049).
- Optional support for position-independent code via a command line option
  -fPIC. This is disabled by default and not required for natdynlink.
- Can emit both ARM and Thumb-2 code, with avg. code size savings of 28% for
  Thumb-2 (quite close the optimal 30% advertised by ARM Ltd.).
- Supports both AAPCS (armel) as well as extended VFP calling conventions
  (armhf).
- Supports several special ARM instructions to reduce code size and latency.
- Uses standard ARM EABI runtime functions instead of relying on GCC internals.
- Supports exception backtraces.
- Supports profiling using gprof.
