[PATCH] New alias analysis for static global variables

[Sam Parker]

I have rewritten the pass as an Immutable pass, as the module pass seemed to get invalidated and hardly ever used.  This does mean that it has to perform the analysis fully every time it is queried, and this increases compilation time of LNT by ~1.1%. It now uses the CaptureTracking system already provided in the LLVM code base.
