add a pass that can extract all kinds of global values, not just functions.  Update llvm-extract to use it and optionally extract a global variable if you want it too

This pass transforms 

  %struct._Point = type { i32, i32, i32, i32, i32, i32 }
  define internal void @foo(%struct._Point* sret  %agg.result)

into

  %struct._Point = type { i32, i32, i32, i32, i32, i32 }
  define internal %struct._Point @foo()

This pass updates foo() clients appropriately to use
getresult instruction to extract return values.

This pass is not yet ready for prime time.

the vector elements.  this means we need to compile the load of the 
array elements into an extract element plus a truncate.
