db78c4873e Add a AccessesArgumentsReadonly ModRefBehavior value, so that the intrinsic 
property IntrReadArgMem can be modeled.

a25e5dbcc2 Extend the AliasAnalysis::pointsToConstantMemory interface to allow it 
to optionally look for constant or local (alloca) memory.

Teach BasicAliasAnalysis::pointsToConstantMemory to look through Select
and Phi nodes, and to support looking for local memory.

Remove FunctionAttrs' PointsToLocalOrConstantMemory function, now that
AliasAnalysis knows all the tricks that it knew.

35fcd6557f Introduce DIBuilder. It is intended to be a front-end friendly interface to emit debuggging information entries in LLVM IR. 
To create debugging information for a pointer, using DIBUilder front-end just needs
	DBuilder.CreatePointerType(Ty, Size);
instead of
	DebugFactory.CreateDerivedType(llvm::dwarf::DW_TAG_pointer_type,
                                       TheCU, "", getOrCreateMainFile(),
                                       0, Size, 0, 0, 0, OCTy);

081c34b725 Get rid of static constructors for pass registration. Instead, every pass exposes an initializeMyPassFunction(), which 
must be called in the pass's constructor.  This function uses static dependency declarations to recursively initialize
the pass's dependencies.

Clients that only create passes through the createFooPass() APIs will require no changes.  Clients that want to use the
CommandLine options for passes will need to manually call the appropriate initialization functions in PassInitialization.h
before parsing commandline arguments.

I have tested this with all standard configurations of clang and llvm-gcc on Darwin.  It is possible that there are problems
with the static dependencies that will only be visible with non-standard options.  If you encounter any crash in pass
registration/creation, please send the testcase to me directly.
