Hi,

Attached is a patch to check that a nonlocal label doesn't appear in
the middle of a basic block.

Note that we don't consider a nonlocal label to be appearing in the
middle of a basic block if all the statements before the label are
also nonlocal labels.

This patch is based on the thread starting at

http://gcc.gnu.org/ml/gcc/2005-01/msg01036.html

Unfortunately, this patch introduces the following regressions (or
rather catches the following errors that went undetected previously).

I already know what is causing them, I will look into this problem soon since I caused them.
