There was a large performance regression that was bisected to commit 611ae8e3
(x86/tlb: enable tlb flush range support for x86). This patch simply changes
the default balance point between a local and global flush for IvyBridge.

In the interest of allowing the tests to be reproduced, this patch was
tested using mmtests 0.15 with the following configurations

        configs/config-global-dhp__tlbflush-performance
        configs/config-global-dhp__scheduler-performance
        configs/config-global-dhp__network-performance


Based on these results, changing the default for Ivybridge seems
like a logical choice.
