One of the main features of Systemtap's SDT probes is the ability to pass
arguments to a probe. Those arguments are stored in the processor's
registers, which can be read by other tools through information
available on the SDT note. This commit adds the same functionality,
although the current implementation only works on x86_64. In the future,
we should add support for other processors.
