While both GlobalAlias and GlobalIFunc are GlobalIndirectSymbol, their `getIndirectSymbol()` usage is quite different (GlobalIFunc's resolver is an entity different from GlobalIFunc itself). As discussed on https://lists.llvm.org/pipermail/llvm-dev/2020-September/144904.html ("[IR] Modelling of GlobalIFunc"), the name `getBaseObject` is confusing when used with GlobalIFunc. To resolve the confusion: * Move GloalIndirectSymol::getBaseObject to GlobalAlias:: (GlobalIFunc should use `getResolver` instead) * Change GlobalValue::getBaseObject not to inspect GlobalIFunc. Note: the function has 7 references. * Add GlobalIFunc::getResolverFunction to peel off potential ConstantExpr indirection (`strlen` in `test/LTO/Resolution/X86/ifunc.ll`) Note: GlobalIFunc::getResolver (like GlobalAlias::getAliasee which does not peel off ConstantExpr indirection) is kept to be used by ValueEnumerator.
