Introduce Simple Analysis interface for loop passes.
...
Right now, this interface provides hooks for only to operations, 1) clone basic block 2) delete value.

Add a SCEV class and supporting code for sign-extend expressions.

This created an ambiguity for expandInTy to decide when to use
sign-extension or zero-extension, but it turns out that most of its callers
don't actually need a type conversion, now that LLVM types don't have
explicit signedness. Drop expandInTy in favor of plain expand, and change
the few places that actually need a type conversion to do it themselves.

For PR780:
...
1. Move IncludeFile.h to System library
2. Move IncludeFile.cpp to System library
3. #1 and #2 required to prevent cyclic library dependencies for libSystem
4. Convert all existing uses of Support/IncludeFile.h to System/IncludeFile.h
5. Add IncludeFile support to various lib/System classes.
6. Add new lib/System classes to LinkAllVMCore.h
All this in an attempt to pull in lib/System to what's required for VMCore

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.
This fixes PR827 and Transforms/Inline/2006-07-12-InlinePruneCGUpdate.ll

Do partial inlining in BU. This resolves more call sites. Also add options to merge in globals during recursion and to back annotate DSNodes when function pointers are resolved. This makes PA work for a whole lot more things (unresolved call sites being what has been killing various DSA based passes)

For PR780:
...
1. Fix the macros in IncludeFile.h to put everything in the llvm namespace
2. Replace the previous explicit mechanism in all the .h and .cpp files
with the macros in IncludeFile.h
This gets us a consistent mechanism throughout LLVM for ensuring linkage.
Next step is to make sure its used in enough places.
