Add a version of Intrinsic::getName which is more efficient when there are no overloads.
When running 'opt -O2 verify-uselistorder-nodbg.lto.bc', there are 33m allocations. 8.2m
come from std::string allocations in Intrinsic::getName(). Turns out this method only
returns a std::string because it needs to handle overloads, but that is not the common case.
This adds an overload of getName which just returns a StringRef when there are no overloads
and so saves on the allocations.
