591bfa1e0b Changes to support making the shift instructions be true BinaryOperators.
This feature is needed in order to support shifts of more than 255 bits
on large integer types.  This changes the syntax for llvm assembly to
make shl, ashr and lshr instructions look like a binary operator:
   shl i32 %X, 1
instead of
   shl i32 %X, i8 1
Additionally, this should help a few passes perform additional optimizations.

issues when they see them. All changes pass DejaGnu tests and Olden.

e5e2e8d917 Change the callgraph representation to store the callsite along with the
target CG node.  This allows the inliner to properly update the callgraph
when using the pruning inliner.  The pruning inliner may not copy over all
call sites from a callee to a caller, so the edges corresponding to those
call sites should not be copied over either.

1. Fix the macros in IncludeFile.h to put everything in the llvm namespace

bc04a6c143 Since there was interest on the mailing list, this is a utility pass that
