- created new testbench file instead of having it at the bottom of the srt file
...
- uses unpacker to parse 64 bit floating point numbers
- updated testbench to read from new testvectors generated by exptestbench
Notes:
MEM_WIDTH updated to be 64*3
Input numbers and output result is 64 bit number
MEM_SIZE set to 60000

- may be a better implementation of the exponent module rather than
having what I believe are two adders currently

Modified lsu and uncore so only 1 sww is present. The sww is in the LSU if there is a cache or dtim. uncore.sv contains the sww if there is no local memory in the LSU. This is necessary as the subword write needs the read data to be valid and that read data is not aviable in the correct cycle in the LSU if there is no dtim or cache. Muxing could be done to provide the correct read data, but it adds muxes to the critical path.
