Fix #93947: the cycle detection mechanism added by https://reviews.llvm.org/D37524 also disallowed including a file twice, which is an unnecessary limitation. Now that we have an include stack #100493, supporting multiple inclusion is trivial. Note: a filename can be referenced with many different paths, e.g. a.lds, ./a.lds, ././a.lds. We don't attempt to detect the cycle in the earliest point.
