Remove lifetime markers completely for variables that are declared after a label was seen in a compound statement

I tested this patch building llvm's test-suite and SPEC benchmarks with -Os. Surprisingly (maybe not so surprising), none of the 3000+ object files changed, so I think removing the markers should be fine at least for now.
