convert one test to use this. This is a particularly significant milestone because it required a working per-function AA framework which can be queried over each function from within a CGSCC transform pass (and additionally a module analysis to be accessible). This is essentially *the* point of the entire pass manager rewrite. A CGSCC transform is able to query for multiple different function's analysis results. It works. The whole thing appears to actually work and accomplish the original goal. While we were able to hack function attrs and basic-aa to "work" in the old pass manager, this port doesn't use any of that, it directly leverages the new fundamental functionality. For this to work, the CGSCC framework also has to support SCC-based behavior analysis, etc. The only part of the CGSCC pass infrastructure not sorted out at this point are the updates in the face of inlining and running function passes that mutate the call graph. The changes are pretty boring and boiler-plate. Most of the work was factored into more focused preperatory patches. But this is what wires it all together. llvm-svn: 261203
