c9c191c41b Reversed the order of the llvm.writeport() operands so that the value 
is listed first and the address is listed second.

07c581695d Added the llvm.readport and llvm.writeport intrinsics. 
The Verifier ensures that their parameters are of integral types and have
the correct sign, but it does not enforce any size restrictions because
such restrictions are platform dependent.

    to fill in
  - Pass's now specify which other passes they _preserve_ not which ones
    they modify (be conservative!)
  - A pass can specify that it preserves all analyses (because it never
    modifies the underlying program)
