cpu defs: add pse36, mca, mtrr to AMD CPU definitions (v2)

This patch adds some missing flags to extfeature_edx, that were missing
according to AMD's latest CPUID document.

This is based on a previous patch from John Cooper where this was introduced
with many other changes at the same time. Original John's patch submission is
at Message-ID: <4DDAD5E7.2020002@redhat.com>, <http://marc.info/?l=qemu-devel&m=130618871926030>.

Original John's patch description was:

    cpu model bug fixes and definition corrections

    This patch was intended to address the replicated feature
    flags in cpuid 8000_0001:edx from cpuid 0000_0001:edx.
    This is due to AMD's definition where these flags are
    mostly cloned in the 8000_0001:edx cpuid function.
    qemu64 attempted to glue together the respective Intel
    and AMD nearly disjoint features and this propagated to
    the new Intel models as doing so was believed conservative
    at the time.  However after further soak and test lugging
    around this cruft doesn't provide any value, could
    conceivably confuse a guest, and has confused users trying
    to maintain/add cpu definitions.  This also caused issues
    for libvirt attempting to track this mis-encoding.

    So we've here tossed out the AMD replicated definitions
    from the Intel models, added a few replications into AMD
    definitions which were missing according to AMD's latest
    CPUID document, and reordered the config file flags to
    follow intuitive sequential bit ordering.  Also two flag
    name aliases were added for clarity to Intel models.  The
    end result being the models definitions now conform to
    their respective cpuid specifications sans x2apic which is
    emulated by kvm.

    This was tested with the following combinations:

        [Conroe, Penryn, Nehalem] x [F12-64, win64, win32] -- Intel host
        [Opteron_G1, Opteron_G2, Opteron_G3] x [F12-64, win64, win32] -- AMD host

    Yielding successful boots in all cases.
