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: Introduce X86CPU::filtered_features field

This field will contain the feature bits that were filtered out because
of missing host support.

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,...

target-i386: Add "feature-words" property to X86CPU

This property will be useful for libvirt, as libvirt already has logic
based on low-level feature bits (not feature names), so it will be
really easy to convert the current libvirt logic to something using the...

target-i386: Use FeatureWord loop on filter_features_for_kvm()

Instead of open-coding the filtering code for each feature word, change
the existing code to use the feature_word_info array, that has exactly
the same CPUID eax/ecx/register values for each feature word....

target-i386: Add ECX information to FeatureWordInfo

FEAT_7_0_EBX uses ECX as input, so we have to take that into account
when reporting feature word values.
