add pseduo instruction support for sparc

util/m5/Makefile.alpha:
    Clean up to make it a bit easier to muck with
util/m5/Makefile.alpha:
    Make the makefile more reasonable
util/m5/Makefile.alpha:
    Remove authors from copyright.
util/m5/Makefile.alpha:
    Updated Authors from bk prs info
util/m5/Makefile.alpha:
    bk cp Makefile Makefile.alpha
src/arch/sparc/tlb.cc:
    Clean up the cache code a little bit and make sure the uncacbale bit is set when appropriate
src/arch/alpha/isa/decoder.isa:
src/sim/pseudo_inst.cc:
src/sim/pseudo_inst.hh:
    Rename AlphaPseudo -> PseudoInst since it's all generic
src/arch/sparc/isa/bitfields.isa:
src/arch/sparc/isa/decoder.isa:
src/arch/sparc/isa/includes.isa:
src/arch/sparc/isa/operands.isa:
    Add support for pseudo instructions in sparc
util/m5/Makefile.alpha:
util/m5/Makefile.sparc:
    split off alpha make file and sparc make file for m5 app
util/m5/m5.c:
    ivle and ivlb aren't used anymore
util/m5/m5op.h:
    stdint seems like a more generic better fit here
util/m5/m5op_alpha.S:
    move the op ids into their own header file since we can share them between sparc and alpha
