04f035b8 - [BasicAA] Don't count recursive phi sources as phi sources. (#236650)

[BasicAA] Don't count recursive phi sources as phi sources. (#236650) Allow analyzing a single recursive phi, if all other sources are non-phis. This improves results in a small number of cases and prepares for a follow-up doing additional analysis for multiple phi sources. Improves results in a small number of cases end-to-end, but also prepares for more analysis of other phi sources https://github.com/dtcxzyw/llvm-opt-benchmark-nightly/pull/1878 Compile-time increase is in the noise: https://llvm-compile-time-tracker.com/compare.php?from=97f95cbc330683623836fb24f8c92c619c240a9c&to=5d76c05e0281ab2ab871869be52c7f16cb232484&stat=instructions:u PR: https://github.com/llvm/llvm-project/pull/236650
