    x86: Merge xc_cpu_policy's cpuid and msr objects
    
    Right now, they're the same underlying type, containing disjoint 
information.
    
    Use a single object instead.  Also take the opportunity to rename 'entries' 
to
    'msrs' which is more descriptive, and more in line with nr_msrs being the
    count of MSR entries in the API.
    
    test-tsx uses xg_private.h to access the internals of xc_cpu_policy, so 
needs
    updating at the same time.  Take the opportunity to improve the code clarity
    by passing a cpu_policy rather than an xc_cpu_policy into some functions.
    
    No practical change.  This undoes the transient doubling of storage space 
from
    earlier patches.
