9bb6558a21 target/arm: A32, T32: Create Instruction Syndromes for Data Aborts
Add support for generating the ISS (Instruction Specific Syndrome)
for Data Abort exceptions taken from AArch32. These syndromes are
used by hypervisors for example to trap and emulate memory accesses.

This is the equivalent for AArch32 guests of the work done for AArch64
guests in commit aaa1f954d4.

0a97c40f8e target-arm: Fix aarch64 disas_ldst_single_struct
We add s->be_data within do_vec_ld/st.  Adding it here means that
we have the wrong bits set in SIZE for a big-endian host, leading
to g_assert_not_reached in write_vec_element and read_vec_element.

416d72b97b target-arm: Fix aarch64 vec_reg_offset
Since CPUARMState.vfp.regs is not 16 byte aligned, the ^ 8 fixup used
for a big-endian host doesn't do what's intended.  Fix this by adding
in the vfp.regs offset after computing the inter-register offset.

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.
