[PATCH v2 00/26] target/arm/tcg: Remove inclusions of 'exec/helper-[proto/gen].h'

["Philippe Mathieu-Daudé" <philmd@linaro.org>]

Since v1:
- Addressed rth's review comments (unnecessary helper-gen)
- Added R-b
- Extract M-profile helpers
- Fixed licence in new files

Hi,

This series tries to do what Richard suggested in [*]:

  Targets that have a tcg/ subdir should have helper.h.inc
  moved into there.  At the end, include/exec/helper-gen.h
  and include/exec/helper-proto.h become unused and go away.

but only for the ARM target, to first see if this is heading
in the correct direction.

Instead of having TCG generated helpers included by all
translate/helper units, they are reduced to the few places
really needing them. I expect the build step to be slighly
improved, since the compiler doesn't have to compile and
track unused helpers definitions.
