[IA64] minor performance tune-up in ia64_switch_to
The reenabling of psr.ic should really belong to dtr mapping code block.
It make the fall through code fast since it doesn't need to execute the
predicated-off instruction. Logically make more sense as well since psr.ic
was turned off in .map code block.
