Revert "[SCEVExpander] Add option to preserve LCSSA directly."

This reverts commit 99166fd4fb422351f131fb1265cb85d5f6c5b8da, because it
breaks the polly builders.

polly/test/Isl/CodeGen/invariant_load_escaping_second_scop.ll fails
because a apparently unnecessary LCSSA phi node is introduced.

Make the bots green again, while I take a closer look.
