  target-i386: Rename optimize_flags_init()

Rename the function so that the reason for its existence is
clearer: it does x86-specific initialization of TCG structures.

  target-i386: Fallback vcpu's TSC rate to value returned by KVM

If no user-specified TSC rate is present, we will try to set
env->tsc_khz to the value returned by KVM_GET_TSC_KHZ. This patch
does not change the current functionality of QEMU and just
prepares for later patches to enable migrating vcpu's TSC rate.

  target-i386: Reorganize TSC rate setting code

Following changes are made to the TSC rate setting code in
kvm_arch_init_vcpu():
 * The code is moved to a new function kvm_arch_set_tsc_khz().
 * If kvm_arch_set_tsc_khz() fails, i.e. following two conditions are
   both satisfied:
   * KVM does not support the TSC scaling or it fails to set vcpu's
     TSC rate by KVM_SET_TSC_KHZ,
   * the TSC rate to be set is different than the value currently used
     by KVM, then kvm_arch_init_vcpu() will fail. Prevously,
   * the lack of TSC scaling never failed kvm_arch_init_vcpu(),
   * the failure of KVM_SET_TSC_KHZ failed kvm_arch_init_vcpu()
     unconditionally, even though the TSC rate to be set is identical
     to the value currently used by KVM.

  target-i386: Add support to migrate vcpu's TSC rate

This patch enables migrating vcpu's TSC rate. If KVM on the
destination machine supports TSC scaling, guest programs will
observe a consistent TSC rate across the migration.

If TSC scaling is not supported on the destination machine, the
migration will not be aborted and QEMU on the destination will
not set vcpu's TSC rate to the migrated value.

If vcpu's TSC rate specified by CPU option 'tsc-freq' on the
destination machine is inconsistent with the migrated TSC rate,
the migration will be aborted.

For backwards compatibility, the migration of vcpu's TSC rate is
disabled on pc-*-2.5 and older machine types.
