target-i386: Fix aflag logic for CODE64 and the 0x67 prefix

The code reorganization in commit 4a6fd938 broke handling of PREFIX_ADR.
While fixing this, tidy and comment the code so that it's more obvious
what's going on in setting both aflag and dflag.

The TARGET_X86_64 ifdef can be eliminated because CODE64 expands to the...

target-i386: Fix mask of pte index in memory mapping

Function walk_pte() needs pte index to calculate virtual address.
However, pte index of PAE paging or IA-32e paging is 9 bit, so the mask
should be 0x1ff.

target-i386: fix abort on bad PML4E/PDPTE/PDE/PTE addresses

The code used to walk IA-32e page-tables, and possibly PAE page-tables,
uses the bit mask ~0xfff to get the next PML4E/PDPTE/PDE/PTE address.

However, as we use a uint64_t to store the resulting address, that mask...

target-i386: ROR r8/r16 imm instruction fix

Fix EFLAGS corruption by ROR r8/r16 imm instruction located at the end
of the TB, similarly to commit 089305ac for the non-immediate case.

target-i386: n270 can MOVBE

The Atom core (cpu name "n270" in QEMU speak) supports MOVBE. This is
needed when booting 3.8 and later linux kernels built with the MATOM
target because we require MOVBE in order to boot properly now.

target-i386: Introduce generic CPUID feature compat function

Introduce x86_cpu_compat_set_features(), that can be used to set/unset
feature bits on specific CPU models for machine-type compatibility.

target-i386: Change CPUID model of 486 to 8

This changes the model number of 486 to 8 (DX4) which matches the
feature set presented, and actually has the CPUID instruction.

This adds a compatibility property, to keep model=0 on pc-*-1.4 and older.

target-i386: Emulate X86CPU subclasses for global properties

After initializing the object from its x86_def_t and before setting any
additional cpu arguments, set any global properties for the designated
subclass <name>{i386,x86_64}-cpu.

target-i386: Add "filtered-features" property to X86CPU

This property will contain all the features that were removed from the
CPU because they are not supported by the host.

This way, libvirt or other management tools can emulate the
check/enforce behavior by checking if filtered-properties is all zeroes,...
