The Neon and SVE decoders use private 'plus1' functions to implement
"add one" for the !function decoder syntax. We have a generic
"plus_1" function in translate.h, so use that instead.

Now that we have a common helper, sharing decode does not
save much. Also, this will solve an upcoming naming problem.

The VCMLA and VCADD insns have a size field which is 0 for fp16
and 1 for fp32 (note that this is the reverse of the Neon 3-same
encoding!). Convert it to MO_* values in decode for consistency.

Convert the VFM[AS]L (scalar) insns in the 2reg-scalar-ext group
to decodetree. These are the last ones in the group so we can remove
all the legacy decode for the group.
Note that in disas_thumb2_insn() the parts of this encoding space
where the decodetree decoder returns false will correctly be directed
to illegal_op by the "(insn & (1 << 28))" check so they won't fall
into disas_coproc_insn() by mistake.

Convert the VFM[AS]L (vector) insns to decodetree. This is the last
insn in the legacy decoder for the 3same_ext group, so we can
delete the legacy decoder function for the group entirely.

where the decodetree decoder returns false will correctly be directed
to illegal_op by the "(insn & (1 << 28))" check so they won't fall

Add the infrastructure for building and invoking a decodetree decoder
for the AArch32 Neon encodings. At the moment the new decoder covers
nothing, so we always fall back to the existing hand-written decode.
We follow the same pattern we did for the VFP decodetree conversion
(commit 78e138bc1f672c145ef6ace74617d and following): code that deals
with Neon will be moving gradually out to translate-neon.vfp.inc,
which we #include into translate.c.
In order to share the decode files between A32 and T32, we
split Neon into 3 parts:
* data-processing
* load-store
* 'shared' encodings
The first two groups of instructions have similar but not identical
A32 and T32 encodings, so we need to manually transform the T32
encoding into the A32 one before calling the decoder; the third group
covers the Neon instructions which are identical in A32 and T32.
