0f7faf80 - Attributor: Preserve the function analyses in the light module pass (#240714)

Attributor: Preserve the function analyses in the light module pass (#240714) AttributorLightPass preserved FunctionAnalysisManagerCGSCCProxy, which is meaningless for a module pass, instead of FunctionAnalysisManagerModuleProxy. When the pass changed anything, the module proxy was invalidated, which clears all cached function analyses, so e.g. IPSCCP recomputed the assumption cache, TTI and TLI of every function. The pass neither adds nor removes functions, and it already invalidates the analyses of the functions it changes.
