Chris Lattner 2a7358064e If we are calling an external function, chain to another AA to potentially 
decide, don't just immediately give up.

This implements GlobalsModRef/chaining-analysis.ll

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 a12b5df616 Actually overload the virtual method. This fixes 
Regression/Analysis/GlobalsModRef/purecse.ll.  Isn't this what the
-Woverload-whatever flag would warn about :)

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 d6d99dfa3f Fix a nasty iterator invalidation problem I introduced yesterday. This 
unfortunately is the cause of a bunch of failures from tonight, and the
reason the tester is running so slow :(

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 b696462260 Fix conservative assumption, which was quite broken. Also, notice that 
functions known to not access memory (like sin/cos) don't access memory! :)

Chris Lattner 3a353e84b7 Complete rewrite of this pass to be faster, use less memory, be easier to 
understand, and more accurate to boot!  This implements
GlobalModRef/purecse.ll over the previous impl.

Chris Lattner 26dff501a4 Initial checkin of a simple mod/ref analysis for global variables. This is 
still overly conservative and uses very simple data structures, but it is a
start, and allows elimination of a lot of loads.

Chris Lattner 8b6db18ac3 Change the call graph class to have TWO external nodes, making call graph 
SCC passes much more useful.  In particular, this should fix the incredibly
stupid missed inlining opportunities that the inliner suffered from.
