Now that each domain has a correct view of VMX MSRs in it's per-domain
MSR policy, it's possible to handle guest's RD/WRMSR with the new
handlers. Do it and remove the old nvmx_msr_read_intercept() and
associated bits.
There is no functional change to what a guest sees in VMX MSRs.
Signed-off-by:
Availability of some MSRs depends on certain CPUID bits. Add function
recalculate_domain_msr_policy() which updates availability of per-domain
MSRs based on current domain's CPUID policy. This function is called
when CPUID policy is changed from a toolstack.
Add recalculate_domain_vmx_msr_policy()
With the new cpuid infrastructure there is a domain-wide struct cpuid
policy and there is no need to pass a separate struct vcpu * into
hvm_cr4_guest_valid_bits() anymore. Make the function accept struct
domain * instead and update callers.

Raw policy contains the actual values from H/W MSRs. PLATFORM_INFO msr
needs to be read again because probe_intel_cpuid_faulting() records
the presence of X86_FEATURE_CPUID_FAULTING but not the presence of msr
itself (if cpuid faulting is not available).
Host policy might have certain features dis
Currently, when nested virt is enabled, the set of L1 VMX features
is fixed and calculated by nvmx_msr_read_intercept() as an intersection
between the full set of Xen's supported L1 VMX features, the set of
actual H/W features and, for MSR_IA32_VMX_EPT_VPID_CAP, the set of
features that Xen uses.
Add calculate_raw_vmx_policy() which fills Raw policy with H/W values
of VMX MSRs. Host policy will contain a copy of these values.

New definitions provide a convenient way of accessing contents of
VMX MSRs. They are separated into 5 logical blocks:
1. vmx: [VMX_BASIC, VMX_VMCS_ENUM]
2. VMX_PROCBASED_CTLS2
3. VMX_EPT_VPID_CAP
4. vmx_true_ctls: [VMX_TRUE_PINBASED_CTLS, VMX_TRUE_ENTRY_CTLS]
5. VMX_VMFUNC

The end goal of having VMX MSRs policy is to be able to manage
L1 VMX features. This patch series is the first part of this work.
There is no functional change to what L1 sees in VMX MSRs at this
point. But each domain will have a policy object which allows to
sensibly query what VMX features the d
clang 5.0 changed the layout of the type_mismatch_data structure and
introduced __ubsan_handle_type_mismatch_v1 and
__ubsan_handle_pointer_overflow.
This commit adds support for the new structure layout, adds the
missing handlers and the new types for type_check_kinds.
