The long awaited CAST patch. This introduces 12 new instructions into LLVM
to replace the cast instruction. Corresponding changes throughout LLVM are
provided. This passes llvm-test, llvm/test, and SPEC CPUINT2000 with the
exception of 175.vpr which fails only on a slight floating point output
difference.

to unaliased allocations. Use this information to disambiguate pointers loaded
from them. This is a very common case, so it's worthwhile to handle efficiently.
This implements Analysis/GlobalsModRef/indirect-global.ll

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

Regression/Analysis/GlobalsModRef/purecse.ll. Isn't this what the
-Woverload-whatever flag would warn about :)

Move include/Config and include/Support into include/llvm/Config,
include/llvm/ADT and include/llvm/Support. From here on out, all LLVM
public header files must be under include/llvm/.

understand, and more accurate to boot! This implements
GlobalModRef/purecse.ll over the previous impl.

still overly conservative and uses very simple data structures, but it is a
start, and allows elimination of a lot of loads.
