These were added to the 1.3 spec. For OF32S, validate AVR.
But OF64A32 is itself new to 1.3 so no extra check needed.

This is hardware support for double-precision floating-point using
pairs of 32-bit registers. Fix latent bugs in the heretofore unused
helper_itofd and helper_ftoid. Include the bit for cpu "any".
Change the default cpu for linux-user to "any".

It's either "GNU *Library* General Public version 2" or "GNU Lesser
General Public version *2.1*", but there was no "version 2.0" of the
"Lesser" library. So assume that version 2.1 is meant here.

Rather than pass base+offset to the helper, pass the full index.
In most cases the base is r0 and optimization yields a constant.

The architecture manual is unclear about this, but the or1ksim
does writeback before the exception. This requires splitting
the helpers in half, with the exception raised by the second.

Note that the specification for lf.madd.s is confused. It's
the only mention of supposed FPMADDHI/FPMADDLO special registers.
On the other hand, or1ksim implements a somewhat normal non-fused
multiply and add. Mirror that.

Fix incorrect overflow calculation. Move overflow exception check
to a helper function, to eliminate inline branches. Remove some
incorrect special casing of R0. Implement multiply inline.

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.
