8d3ab25335 Use iterative algorith to assign DFS number. This reduces
call stack depth.

4b8f36f106 Do not rely on std::sort and std::erase to get list of unique
exit blocks. The output is dependent on addresses of basic block.

Add and use Loop::getUniqueExitBlocks.

7107c3badf 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

d85340f4ec 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

ab390d045a 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)

4f1bd9e996 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.

632cd52162 Since there was interest on the mailing list, this is a utility pass that
uses DSA to make find targets of calls.  It provides a very convinient
interface to DSA results to do things with indirect calls, such as
write a devirtualizer (which I have and may commit one of these days).

442b32b5c5 Fix PR681 by using the standard Lengauer and Tarjan algorithm for dominator
set construction, rather than intersecting various std::sets.  This reduces
the memory usage for the testcase in PR681 from 496 to 26MB of ram on my
darwin system, and reduces the runtime from 32.8 to 0.8 seconds on a
2.5GHz G5.  This also enables future code sharing between Dom and PostDom
now that they share near-identical implementations.
