[cmake] Disable GCC lifetime DSE
LLVM data structures like llvm::User and llvm::MDNode rely on
the value of object storage persisting beyond the lifetime of the
object (#24952). This is not standard compliant and causes a runtime
crash if LLVM is built with GCC and LTO enabled (#57740). Until
these issues are fixed, we need to disable dead store eliminations
eliminations based on object lifetime.
The previous test issues are fixed by
