819260ef - [flow-isolation] Rename Info -> BlockInfo, AnalysisInfo -> FunctionInfo

[flow-isolation] Rename Info -> BlockInfo, AnalysisInfo -> FunctionInfo The names `Info` and `AnalysisInfo` were generic and didn't clearly convey the scope of each type. Rename them to `BlockInfo` and `FunctionInfo` to make explicit that `BlockInfo` holds per-basic-block data and `FunctionInfo` holds the analysis state for an entire SILFunction.
