Modified Files:
        src/sys/arch/amd64/amd64: machdep.c
        src/sys/arch/i386/i386: machdep.c
        src/sys/arch/x86/include: cpu.h
        src/sys/arch/x86/x86: fpu.c identcpu.c x86_machdep.c

Log Message:
Determine whether the cpu supports xsave (and hence AVX).
The result is only written to sysctl nodes at the moment.
I see:
machdep.fpu_save = 3 (implies xsaveopt)
machdep.xsave_size = 832
machdep.xsave_features = 7
Completely common up the i386 and amd64 machdep sysctl creation.
