target-i386: kvm: -cpu host: Use GET_SUPPORTED_CPUID for SVM features

The existing -cpu host code simply sets every bit inside svm_features
(initializing it to -1), and that makes it impossible to make the
enforce/check options work properly when the user asks for SVM features...

target-i386: kvm: Enable all supported KVM features for -cpu host

When using -cpu host, we don't need to use the kvm_default_features
variable, as the user is explicitly asking QEMU to enable all feature
supported by the host.

This changes the kvm_cpu_fill_host() code to use GET_SUPPORTED_CPUID to...

target-i386: check/enforce: Fix CPUID leaf numbers on error messages

The -cpu check/enforce warnings are printing incorrect information about the
missing flags. There are no feature flags on CPUID leaves 0 and 0x80000000, but
there were references to 0 and 0x80000000 in the table at...

target-i386: check/enforce: Do not ignore "hypervisor" flag

We don't need any hack to ignore CPUID_EXT_HYPERVISOR anymore, because
kvm_arch_get_supported_cpuid() now sets CPUID_EXT_HYPERVISOR properly.
So, this shouldn't introduce any behavior change, but it makes the code...

target-i386: check/enforce: Check all CPUID.80000001H.EDX bits

I have no idea why PPRO_FEATURES was being ignored on the check of the
CPUID.80000001H.EDX bits. I believe it was a mistake, and it was
supposed to be ~(PPRO_FEATURES & CPUID_EXT2_AMD_ALIASES) or just...

target-i386: check/enforce: Check SVM flag support as well

When nested SVM is supported, the kernel returns the SVM flag on
GET_SUPPORTED_CPUID1, so we can check the SVM flag safely in
kvm_check_features_against_host().

I don't know why the original code ignored the SVM flag. Maybe it was...

target-i386: check/enforce: Eliminate check_feat field

Now that all entries have check_feat=~0 in
kvm_check_features_against_host(), we can eliminate check_feat entirely
and make the code check all bits.

This patch shouldn't introduce any behavior change, as check_feat is set...

target-i386: Sanitize AMD's ext2_features at realize time

When CPU properties are implemented, ext2_features may change
between object_new(CPU) and cpu_realize_fn(). Sanitizing
ext2_features for AMD based CPU at realize() time will keep
current behavior after CPU features are converted to properties....

target-i386: Explicitly set vendor for each built-in cpudef

Since cpudef config is not supported anymore and all remaining sources
now always set x86_def_t.vendor123 fields, remove setting default
vendor to simplify future re-factoring.
