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.

Clean up includes so that osdep.h is included first and headers
which it implies are not included manually.
This commit was created with scripts/clean-includes.

Rather than include helper.h with N values of GEN_HELPER, include a
secondary file that sets up the macros to include helper.h. This
minimizes the files that must be rebuilt when changing the macros
for file N.

Add another slot in ENV and store two of the three inputs. This lets us
do less work when carry-out is not needed, and avoids the unpredictable
CC_OP after translating these insns.

Pass the data in explicitly, rather than indirectly via env.
This avoids all sorts of unnecessary register spillage.

In preparation for making this a const helper.
By using the proper types in the parameters to the helper functions,
we get to avoid quite a lot of subsequent casting.

This patch implements Supervisor Mode Execution Prevention (SMEP) and
Supervisor Mode Access Prevention (SMAP) for x86. The purpose of the
patch, obviously, is to help kernel developers debug the support for
those features.
A fair bit of the code relates to the handling of CPUID features. The
CPUID code probably would get greatly simplified if all the feature
bit words were unified into a single vector object, but in the
interest of producing a minimal patch for SMEP/SMAP, and because I had
very limited time for this project, I followed the existing style.
[ v2: don't change the definition of the qemu64 CPU shorthand, since
that breaks loading old snapshots. Per Anthony Liguori this can be
fixed once the CPU feature set is snapshot.
Change the coding style slightly to conform to checkpatch.pl. ]
