f1661baf30 Fix up microcode support.
src/arch/sparc/isa/formats/blockmem.isa:
    Several small and medium bug fixes.
src/cpu/simple/base.cc:
    Fixed a few compiler errors and made sure the next micro pc is set to 1 to prevent the first microop from executing twice. Also fixed a fetching bug.
src/cpu/thread_state.cc:
    Made sure the microPC and nextMicroPC are initialized properly.

546dff6b6a Made sure the constructor for insts use ExtMachInst rather than MachInst, since otherwise the EXT_ASI field is lost.
src/arch/sparc/isa/base.isa:
src/arch/sparc/isa/formats/micro.isa:
    Switch MachInst to ExtMachInst so that the EXT_ASI field is available to the instructions.
src/arch/sparc/utility.hh:
    Made sure EXT_ASI was set to the appropriate ASI value whether or not the asi register was used.

a50e83c134 Fix assertion. I haven't tested it fully (I can't reproduce Lisa's error) but I believe it should fix what she's running into (which was definitely a bug).
src/cpu/o3/fetch_impl.hh:
    Move assertion to area where it should really always be true.  Sometimes you might recvRetry and not necessarily be blocked (if there was a squash).
