Convert the Neon integer 3-reg-same compare insns VCGE, VCGT,
VCEQ, VACGE and VACGT to decodetree.
Backports commit 727ff1d63213e6666e511956903b9e97a339ec7e from qemu
Convert the Neon integer VMUL, VMLA, and VMLS 3-reg-same inssn to
decodetree.
We don't have a gvec helper for multiply-accumulate, so VMLA and VMLS
need a loop function do_3same_fp(). This takes a reads_vd parameter
to do_3same_fp() which tells it to load the old value into vd before
calling the callback function, in the same way that the do_vfp_3op_sp()
and do_vfp_3op_dp() functions in translate-vfp.inc.c work. (The
only uses in this patch pass reads_vd == true, but later commits
will use reads_vd == false.)
This conversion fixes in passing an underdecoding for VMUL
Backports commit 8aa71ead912ca0a9c0d29b74e0976f91952f950a from qemu
Convert the Neon float VPMIN, VPMAX and VPADD 3-reg-same insns to
decodetree. These are the only remaining 'pairwise' operations,
so we can delete the pairwise-specific bits of the old decoder's
for-each-element loop now.
Backports commit ab978335a56e3618212868fdce3a54217c6e71e6 from qemu
Convert the Neon VADD, VSUB, VABD 3-reg-same insns to decodetree.
We already have gvec helpers for addition and subtraction, but must
add one for fabd.

Convert the Neon VQDMULH and VQRDMULH 3-reg-same insns to
decodetree. These are the last integer operations in the
3-reg-same group.
Backports commit 7ecc28bc72b8033cf4e0c6332135ec20d4125dfb from qemu
Convert the Neon integer VPADD 3-reg-same insns to decodetree. These
are 'pairwise' operations. (Note that VQRDMLAH, which shares the
same primary opcode but has U=1, has already been converted.)
Backports commit fa22827d4eb078b6c58cd3d19af0b50ed951e832 from qemu
Convert the Neon integer VPMAX and VPMIN 3-reg-same insns to

Convert the VQSHL, VRSHL and VQRSHL insns in the 3-reg-same

case of these insns; this commit handles the remaining sizes
Backports commit 6812dfdc6b0286730d6f903ebfbdc4f81b80c29b from qemu
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.)
Backports commit 8e44d03f4b5590e19a4f7910ca1c327609933dd7 from qemu
Convert the 64-bit element insns in the 3-reg-same group

size==0b11.
Backports commit 35d4352fa9e94b35bf17f58181cb16c184b98d56 from qemu
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.

Calling access_el3_aa32ns() works for AArch32 only cores

and only use the latter.

For the benefit of compatibility of function pointer types,
