LOG: [clang] Replace PointerUnion::dyn_cast with llvm::dyn_cast (NFC) (#230911)

PointerUnion::dyn_cast has been soft-deprecated in favor of
llvm::dyn_cast and llvm::dyn_cast_if_present.  This patch replaces the
former with llvm::dyn_cast where the operand is guaranteed to be
nonnull.

Note that PlaceholderBase::ParamOrMethod is always initialized to a
nonnull pointer in LoanManager::getOrCreatePlaceholderBase and never
modified afterward.
