6089030c73 arm/translate-a64: add FP16 x2 ops for simd_indexed
A bunch of the vectorised bitwise operations just operate on larger
chunks at a time. We can do the same for the new half-precision
operations by introducing some TWOHALFOP helpers which work on each
half of a pair of half-precision operations at once.

Hopefully all this hoop jumping will get simpler once we have
generically vectorised helpers here.

As some of the constants here will also be needed
elsewhere (specifically for the upcoming SVE support) we move them out
to softfloat.h.

d32adeae1a arm/translate-a64: add FP16 F[A]C[EQ/GE/GT] to simd_three_reg_same_fp16
These use the generic float16_compare functionality which in turn uses
the common float_compare code from the softfloat re-factor.

The fprintf is only there for debugging as the skeleton is added to,
it will be removed once the skeleton is complete.

807cdd5042 arm/translate-a64: implement half-precision F(MIN|MAX)(V|NMV)
This implements the half-precision variants of the across vector
reduction operations. This involves a re-factor of the reduction code
which more closely matches the ARM ARM order (and handles 8 element
reductions).

fcf5ef2ab5 Move target-* CPU file into a target/ folder
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.
