replace blocks with Bad's anymore. Instead, the blocks are just marked dead.
Further, blocks with only dead inputs and self recursions are detected as dead.

This seems to help gcc to pass the SPEC00 benchmark.

[r4536]

This attribute can only be set, not reseted and means the block is dead
(could be replaced my Bad in old semantics).

the new is_Block_dead() test chescks for the new attribute (and is_Bad() too)
and should be used whenever a block is check with is_Bad()
