Modify ISA and staticInst to support a IsFirstMicroOp flag

Browse Source 
Increment instruction count on first micro-op instead of last

src/arch/sparc/isa/decoder.isa:
    Implement a twin load for ASI_LDTX_P(0xe2)
src/arch/sparc/isa/formats/mem/blockmem.isa:
    set the new flag IsFirstMicroOp when needed
src/cpu/simple/atomic.cc:
    Increment instruction count on first micro-op instead of last (because if we take a fault on a micro coded instruction it should be counted twice acording to legion)
src/cpu/static_inst.hh:
    Add IsFirstMicroop flag to static insts
