  Revert "[cmake] Disable GCC lifetime DSE"

This reverts commit ce990b542617e5b52f69707b103a2424bec5e53b.

This breaks some build bots - specifically when using GCC to build LLVM and
then -fno-lifetime-dse ends up passed to Clang in some tests like at
https://lab.llvm.org/buildbot/#/builders/139/builds/40594.
