LLVM-GCC does not generate llvm.dbg.region.start

I do not see llvm-gcc generating llvm.dbg.region.start/end pairs for
blocks.
Why?

I'm not sure off-hand. I don't think that the dwarf emitter supports them yet, so llvm-gcc probably just doesn't bother producing them.

Well, its quite easy for clang to produce them. We have EmitCompoundStmt
for a {...}.
So I am going ahead and emit them too.

Ok!
