Chris Lattner 531f9e92d4 This mega patch converts us from using Function::a{iterator|begin|end} to
using Function::arg_{iterator|begin|end}.  Likewise Module::g* -> Module::global_*.

This patch is contributed by Gabor Greif, thanks!

Chris Lattner 244031d306 Argument promotion transforms functions to unconditionally load their
argument pointers.  This is only valid to do if the function already
unconditionally loaded an argument or if the pointer passed in is known
to be valid.  Make sure to do the required checks.

This fixed ArgumentPromotion/control-flow.ll and the Burg program.

Chris Lattner 4f2cf030e8 'Pass' should now not be derived from by clients. Instead, they should derive
from ModulePass.  Instead of implementing Pass::run, then should implement
ModulePass::runOnModule.

Chris Lattner 37b6c4f2d2 Convert this pass to be a CallGraphSCCPass instead of a Pass, which eliminates
the worklist and makes it more efficient.  This does not change functionality
at all.

Reid Spencer 7c16caa336 Changes For Bug 352
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/.

Chris Lattner 1c676f76b6 Make order of argument addition deterministic. In particular, the layout
of ConstantInt objects in memory used to determine which order arguments
were added in in some cases.

Chris Lattner 254f8f8ad5 Fairly substantial changes to update the alias analysis we are querying as
we make the transformation.  This allows us to use interprocedural alias
analyses successfully.

Chris Lattner fe6f2e3e80 Implement ArgumentPromotion/aggregate-promote.ll
This allows pointers to aggregate objects, whose elements are only read, to
be promoted and passed in by element instead of by reference.  This can
enable a LOT of subsequent optimizations in the caller function.

It's worth pointing out that this stuff happens a LOT of C++ programs, because
objects in templates are generally passed around by reference.  When these
templates are instantiated on small aggregate or scalar types, however, it is
more efficient to pass them in by value than by reference.

This transformation triggers most on C++ codes (e.g. 334 times on eon), but
does happen on C codes as well.  For example, on mesa it triggers 72 times,
and on gcc it triggers 35 times.  this is amazingly good considering that
we are using 'basicaa' so far.
