+Guest has no "xsave" feature with parameter "-cpu qemu64,+xsave" in qemu command line.

+Environment:

+qemu-kvm Commit:98f1f30a89901c416e51cc70c1a08d9dc15a2ad4
+Host Kernel Version:3.5.0-rc1
+Hardware:Romley-EP, Ivy-bridge
+
+
+Bug detailed description:
+--------------------------
+Guest has no "xsave" feature when create guest with parameter "-cpu qemu64,+xsave,+avx" in qemu command line, but the guest has avx feature.
+When starting a guest with parameter "-cpu host" in qemu command line, the guest has 'avx' and 'xsave' features (as /proc/cpuinfo shows).
+
+This is not a recent regression; it exists for a long time.
+
+Reproduce steps:
+----------------
+1. qemu-system-x86_64 -m 1024 -smp 2 -hda rhel6u3.img -cpu qemu64,+xsave
+2. cat /proc/cpuinfo | grep xsave     ( check guest's xsave feature)
+
+Current result:
+----------------
+The guest has no xsave feature
+
+Expected result:
+----------------
+The guest has xsave feature
+
+Basic root-causing log:
+
+xsave needs level >= 13, and qemu64 has level=4. Try "-cpu qemu64,+xsave,+avx,level=13".
