oprofile: add support for Intel processor model 30

Newer Intel processors identifying themselves as model 30 are not recognized by
oprofile.

<cpuinfo snippet>
model           : 30
model name      : Intel(R) Xeon(R) CPU           X3470  @ 2.93GHz
</cpuinfo snippet>

Running oprofile on these machines gives the following:
+ opcontrol --init
+ opcontrol --list-events
oprofile: available events for CPU type "Intel Architectural Perfmon"

See Intel 64 and IA-32 Architectures Software Developer's Manual
Volume 3B (Document 253669) Chapter 18 for architectural perfmon events
This is a limited set of fallback events because oprofile doesn't know your CPU
CPU_CLK_UNHALTED: (counter: all)
        Clock cycles when not halted (min count: 6000)
INST_RETIRED: (counter: all)
        number of instructions retired (min count: 6000)
LLC_MISSES: (counter: all)
        Last level cache demand requests from this core that missed the LLC
(min count: 6000)
        Unit masks (default 0x41)
        ----------
        0x41: No unit mask
LLC_REFS: (counter: all)
        Last level cache demand requests from this core (min count: 6000)
        Unit masks (default 0x4f)
        ----------
        0x4f: No unit mask
BR_MISS_PRED_RETIRED: (counter: all)
        number of mispredicted branches retired (precise) (min count: 500)
+ opcontrol --shutdown

Tested using oprofile 0.9.6.
