b12914bfc0 '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.

5eb6f6c829 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.

551ccae044 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/.

beabf45a69 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.

9e7cc2f0d4 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.

9440db8866 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.

ed570a7dca New LLVM pass: argument promotion. This version only handles simple scalar
variables.
