Made the "data" field of store queue entries into a character array. It's sized to match an IntReg which was what it used to be, but we might want to make it something architecture independent. All data is now endian converted before entering the store queue entries which simplifies store to load forwarding in "trans endian" simulations, and makes twin memory ops work.

Made the MultiOp format do a little more. It now sets up single microop instructions to return an instance of the right class. The code to decode register numbers and generate loads and stores still needs to be added. Also, a syntax for specifying operands as sources, destinations, or both needs to be established. Multipl microop instructions are also not handled, pending real macroop generation support.

Add a microcode assembler. A microcode "program" is a series of statements. Each statement has an optional label at the beginning, a capitilized microcode class name which is roughly equivalent to a mnemonic in a regular ISA, and then an optional series of operands seperated by white space. The operands are either a decimal constant, a label, or a code fragment surrounded by non nested {}s. Labels are a letter or underscore followed by letters, underscores, or digits. The syntax for describing code segments might need to be changed if a need arrises to have {}s in the code itself.

Updates for commit.
...
1. Move interrupt handling to a separate function to clean up main commit() function a bit. Also gate the function call off properly based on whether or not there are outstanding interrupts, and the system is not in PAL mode.
2. Better handling of updating instruction's status bits. Instructions are not marked "atCommit" until other stages view it (pushed off to IEW/IQ), and they have been properly handled (faults).
3. Don't consider the ROB "empty" for the purpose of other stages until the ROB is empty, all stores have written back, and there was no store commits this cycle. The last is necessary in case a store committed, in which case it would look like all stores have written back but in actuality have not.
src/cpu/o3/commit.hh:
Slightly modify how interrupts are handled. Also include some extra bools to keep track of state properly.
src/cpu/o3/commit_impl.hh:
