ruby: profiler: lots of inter-related changes
The patch started of with removing the global variables from the profiler for
profiling the miss latency of requests made to the cache. The corrresponding
histograms have been moved to the Sequencer. These are combined together when
the histograms are printed.

A particular set of histograms used to use the Generic Machine Type defined
in one of the protocol files. This patch removes this type. Now, everything
that relied on this type would use MachineType instead. To do this, SLICC
has been changed so that multiple machine types can be declared by a
controller in its preamble.
