Rollup merge of #108891 - kazutakahirata:master, r=cuviper

Remove an extraneous include

SymbolWrapper.cpp doesn't use std::optional or llvm::Optional, so this patch removes the extraneous include.  Note that llvm/ADT/Optional.h has been deprecated upstream.  This patch ensures that SymbolWrapper.cpp continues to compile even after the upcoming removal of Optional.h.
