5f551d9ca2 1. Got rid of unused functions in DirectoryMemory 
2. Reintroduced RMW_Read and RMW_Write
3. Defined -2 in the Sequencer as well as made a note about mandatory queue

Did not address the issues in the slicc because remaking the atomics altogether to allow
multiple processors to issue atomic requests at once

d51445490d regression: updated memtest-ruby stats 
This also includes a change to the default Ruby random seed, which was
previously set using the wall clock.  It is now set to 1234 so that
the stat files don't change for the regression tester.

60577eb4ca ISAs: Get rid of the IControl operand type. 
A separate operand type is not necessary to use two bitfields to generate the
index.

64fe7af51a SPARC: Set up a lookup table for integer register flattening. 
Using a look up table changed the run time of the SPARC_FS solaris boot
regression from:

real    14m45.951s
user    13m57.528s
sys     0m3.452s

to:

real    12m19.777s
