Hi,
tree-ssa rewriter allocates arrays by n_basic_blocks size and then
access it using bb indexes creating interesting memory corruptions on
profiling branch.  I don't have testcase reproducing on tree-ssa
(perhaps blocks happens to be always compacted), but still I would like
to apply it.  OK?

I just encountered this on lno branch in my local sources. First part of patch is necessary to fix memory corruption I am seeing. It occurs when rewrite_into_ssa() is called after few basic blocks are removed from CFG.

Thanks,
