refscale: Add local_irq_disable() and local_irq_save() readers

This commit adds refscale readers based on local_irq_disable() and
local_irq_enable() ("refscale.scale_type=irq") and on local_irq_save()
and local_irq_restore ("refscale.scale_type=irqsave").  On my x86 laptop,
these are about 2.8ns and 7.5ns per enable/disable pair, respectively.
