the result of the operation.

As cpu.h is another typically widely included file which doesn't need
full access to the softfloat API we can remove the includes from here
as well. Where they do need types it's typically for float_status and
the rounding modes so we move that to softfloat-types.h as well.
As a result of not having softfloat in every cpu.h call we now need to
add it to various helpers that do need the full softfloat.h
definitions.
Backports commit 24f91e81b65fcdd0552d1f0fcb0ea7cfe3829c19 from qemu
GCC 4.7.2 on SunOS reports that the values assigned to array members are not
real constants:
target/m68k/fpu_helper.c:32:5: error: initializer element is not constant
target/m68k/fpu_helper.c:32:5: error: (near initialization for 'fpu_rom[0]')
rules.mak:66: recipe for target 'target/m68k/fpu_helper.o' failed
Convert the array to make_floatx80_init() to fix it.
Replace floatx80_pi-like constants with make_floatx80_init() as they are
defined as make_floatx80().
This fixes build on SmartOS (Joyent).
Backports commit 6fa9ba09dbf4eb8b52bcb47d6820957f1b77ee0b from qemu
Add fsabs, fdabs, fsneg, fdneg, fsmove and fdmove.
The value is converted using the new floatx80_round() function.

fmovecr moves a floating point constant from the
FPU ROM to a floating point register.
Backports commit 9d403660d91229922c2786e81c23cc9dd8e644f1 from qemu
Coldfire uses float64, but 680x0 use floatx80.
This patch introduces the use of floatx80 internally
and enables 680x0 80bits FPU.
