Convert the Neon VRHADD and VHSUB 3-reg-same insns to decodetree.
(These are all the other insns in 3-reg-same which were using
GEN_NEON_INTEGER_OP() and which are not pairwise or
reversed-operands.)

Convert the 64-bit element insns in the 3-reg-same group
to decodetree. This covers VQSHL, VRSHL and VQRSHL where
size==0b11.

Convert the Neon VQRDMLAH and VQRDMLSH insns in the 3-reg-same group
to decodetree. These don't use do_3same() because they want to
operate on VFP double registers, whose offsets are different from the
neon_reg_offset() calculations do_3same does.
Backports commit a063569508af8295cf6271e06700e5b956bb402d from qemu
Pass a pointer directly to env->vfp.qc[0], rather than env.
This will allow SVE2, which does not modify QC, to pass a
pointer to dummy storage.
Change the return type of inl_qrdml.h_s16 to match the
sense of the operation: signed.

Rather than perform the argument swap during code generation,
perform it during decode. This means it doesn't have to be
special cased later, and we can share code with aarch64 code
generation. Hopefully the decode comment addresses any confusion
that might arise in between.

Now that we've converted all cases to gvec, there is quite a bit
of dead code at the end of the function. Remove it.
Sink the call to gen_gvec_fn2i to the end, loading a function
pointer within the switch statement.

In 1dc8425e551, while converting to gvec, I added an extra range check
against the shift count. This was unnecessary because the encoding of
the shift count produces 0 to the element size - 1.
Backports commit 2f27c5244db300387f15d9ffa5067a204ffd625d from qemu
The functions eliminate duplication of the special cases for
this operation. They match up with the GVecGen2iFn typedef.
Add out-of-line helpers. We got away with only having inline
expanders because the neon vector size is only 16 bytes, and
we know that the inline expansion will always succeed.
When we reuse this for SVE, tcg-gvec-op may decide to use an
out-of-line helper due to longer vector lengths.

Create vectorized versions of handle_shri_with_rndacc

DUP (indexed) can duplicate 128-bit elements, so using esz

Calling access_el3_aa32ns() works for AArch32 only cores
but it does not handle 32-bit EL2 on top of 64-bit EL3
for mixed 32/64-bit cores.
Merge access_el3_aa32ns_aa64any() into access_el3_aa32ns()
and only use the latter.

For the benefit of compatibility of function pointer types,
we have standardized on int32_t and int64_t as the integral
argument to tcg expanders.
We converted most of them in 474b2e8f0f7, but missed the rotates.

Add a version of tcg_gen_dup_* that takes both immediate and

tcg_gen_gvec_dup{8,16,32,64}i functions that encode the element
size within the function name.

We're going to want at least some of the NeonGen* typedefs

to translate.h since it makes more sense to keep them in
one group.

Convert the Neon logic ops in the 3-reg-same grouping to decodetree.
Note that for the logic ops the 'size' field forms part of their
decode and the actual operations are always bitwise.

Convert the Neon 3-reg-same VADD and VSUB insns to decodetree.
Note that we don't need the neon_3r_sizes[op] check here because all
size values are OK for VADD and VSUB; we'll add this when we convert
the first insn that has size restrictions.
For this we need one of the GVecGen*Fn typedefs currently in
translate-a64.h; move them all to translate.h as a block so they
are visible to the 32-bit decoder.

As this is the last set of insns in the neon load/store group,
