8561c8366c fix smul and sdiv to sign extend, and handle overflow/underflow corretly
Only allow writing/reading of 32 bits of Y
Only allow writing/reading 32 bits of pc when pstate.am
Put any loaded data on the first half of a micro-op in uReg0 so it can't
overwrite the register we are using for address calculation
only erase a entry from the lookup table if it's valid
Put in a temporary check to make sure that lookup table and tlb array stay in sync
if we are interrupted in the middle of a mico-op, reset the micropc/nexpc
so we start  on the first part of it when we come back

6aa06a26b7 Changes to the isa_parser and affected files to fix an indexing problem with split execute instructions and miscregs aliasing with integer registers.
src/arch/isa_parser.py:
    Rearranged things so that classes with more than one execute function treat operands properly.
    1. Eliminated the CodeBlock class
    2. Created a SubOperandList
    3. Redefined how InstObjParams is constructed

    To define an InstObjParam, you can either pass in a single code literal which will be named "code", or you can pass in a dictionary of code snippets which will be substituted into the Templates. In order to get this to work, there is a new restriction that each template has only one function in it. These changes should only affect memory instructions which have regular and split execute functions.

    Also changed the MiscRegs so that they use the instrunctions srcReg and destReg arrays.

98b00d92fd Some support for handling block loads and stores and ASIs properly.
src/arch/sparc/isa/bitfields.isa:
    Added a field to retrieve the asi from the ExtMachInst
src/arch/sparc/isa/decoder.isa:
    Fixed up how the size of memory operations where handled, and use the new EXT_ASI bit field.
src/arch/sparc/isa/formats.isa:
    add includes for the new formats.
src/arch/sparc/isa/formats/basic.isa:
    Add a template for BasicDecodeWithMnemonic which is needed by the unimp format.
src/arch/sparc/isa/formats/mem.isa:
    Change around the memory format to figure out the memory access width on its own.
src/arch/sparc/isa/operands.isa:
    Added support for the operands of block loads/stores which are offset from Frd.
src/arch/sparc/utility.hh:
    Encoded the ASI into the ExtMachInst

1. alignaddr wrote it's address to a floating point register rather than a gpr.
2. sethi was sign extending it's immediate value.
