Forgetting to adding feature names to the feature array
seems to be a very common mistake.

Examples:

- Missing name for MSR_VMX_EPT_WB
  commit 0723cc8a5558 ("target/i386: add VMX features to named CPU models")
- Missing name for "ibrs" at
  https://lore.kernel.org/qemu-devel/0ad4017d-e755-94a3-859e-800661bcd2d1@amd.com

This series fixes the MSR_VMX_EPT_WB problem and adds a runtime
check that should detect similar mistakes even before CPU model
classes are registered.

Eduardo Habkost (3):
  i386: Add missing "vmx-ept-wb" feature name
  i386: Move asserts to separate x86_cpudef_validate() function
  i386: Sanity check CPU model feature sets
