[Bug bootstrap/34255] New: scope-blocks-on-a-diet patch diverges -g from non-g output code

["aoliva at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

http://gcc.gnu.org/ml/gcc-patches/2007-07/msg01745.html regresses the property
that code output with -g must be the same as that without -g.  make
bootstrap-debug demonstrates that several files miscompare after this patch,
and don't if the patch is reversed.

The patch not only causes -g divergence, it also accidentally drops subblocks
that need to be kept around for the sake of generating debug information for
them.

Both problems are fixed with the patch at
