Hi Isaku

This is only used by __kernel_syscall_via_epc function in xeno domain. 
previouly,  break 0x19(XEN_HYPER_GET_PSR) is the second
Instruction in the bundle.

When I debugged the patch of remove the requirement (vpsr.ic==0) 
fromhyperprivop.
break 0x19 is the third instruction in the bundle, this causes dom0 can't boot.
This patch can resolve this.
And this is correct emulation of mov from psr.
