e4d5c441e0 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!

a990d94330 If a function always returns a constant, replace all calls sites with that 
constant value.  This makes the return value dead and allows for
simplification in the caller.

This implements IPConstantProp/return-constant.ll

This triggers several dozen times throughout SPEC.

d79c7b43f4 Actually, leave the check in. This prevents us from counting dead arguments 
as IPCP opportunities.

ff1529b6cf Make IP Constant prop more aggressive about handling self recursive calls. 
This implements IPConstantProp/recursion.ll

c890bfe1da Do not let dead constant expressions hanging off of functions prevent IPCP. 
This allows to elimination of a bunch of global pool descriptor args from
programs being pool allocated (and is also generally useful!)

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.

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/.

2e8dfb8221 Propagating constants to arguments can make other arguments constant. For now 
do something dumb, and inefficient, but more complete.
