Backports commit 591596b77a1872d0652e666271ca055e57ea1e21 from qemu
Add the third stack pointer, the Interrupt Stack Pointer (ISP)
(680x0 only). This stack will be needed in softmmu mode.
Update movec to set/get the value of the three stacks.

The instruction traps if the CPU is not in
Supervisor state but the helper is empty because
there is no easy way to reset all the peripherals
without resetting the CPU itself.
Backports commit 0bdb2b3bf5660f892ddbfa09baea56cdca57ad1d from qemu
chk and chk2 compare a value to boundaries, and
trigger a CHK exception if the value is out of bounds.

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.

Coldfire uses float64, but 680x0 use floatx80.
This patch introduces the use of floatx80 internally
and enables 680x0 80bits FPU.
Backports commit f83311e4764f1f25a8abdec2b32c64483be1759b from qemu
We've currently got 18 architectures in QEMU, and thus 18 target-xxx
folders in the root folder of the QEMU source tree. More architectures
(e.g. RISC-V, AVR) are likely to be included soon, too, so the main
folder of the QEMU sources slowly gets quite overcrowded with the
target-xxx folders.
To disburden the main folder a little bit, let's move the target-xxx
folders into a dedicated target/ folder, so that target-xxx/ simply
becomes target/xxx/ instead.
