Revert "ignore already seen locations in compiler plugins"

This does not always work well, e.g. when building a return value
in a return statement from a temporary, there is CXXConstructExpr
containing CXXTemporaryObjectExpr, which both share the same location.
This reverts commit 1c0669af2f1f58e6431b5e489ac48a883e242ba7.
