Juergen Gross 94a992bccd xen/x86: use invpcid for flushing the TLB
If possible use the INVPCID instruction for flushing the TLB instead of
toggling cr4.pge for that purpose.

While at it remove the dependency on cr4.pge being required for mtrr
loading, as this will be required later anyway.

Add a command line option "invpcid" for controlling the use of
INVPCID (default to true).
