tree-optimization/106722 - avoid invalid pointer association in predcom
When predictive commoning builds a reference for iteration N it
prematurely associates a constant offset into the MEM_REF offset
operand which can be invalid if the base pointer then points
outside of an object which alias-analysis does not consider valid.
PR tree-optimization/106722
* tree-predcom.cc (ref_at_iteration): Do not associate the
constant part of the offset into the MEM_REF offset
operand, across a non-zero offset.
* gcc.dg/torture/pr106892.c: New testcase.

tree-optimization/106722 - fix CD-DCE edge marking
The following fixes a latent issue when we mark control edges but
end up with marking a block with no stmts necessary. In this case
we fail to mark dependent control edges of that block.
PR tree-optimization/106722
* tree-ssa-dce.cc (mark_last_stmt_necessary): Return
whether we marked a stmt.
(mark_control_dependent_edges_necessary): When
mark_last_stmt_necessary didn't mark any stmt make sure
to mark its control dependent edges.
(propagate_necessity): Likewise.
* gcc.dg/torture/pr108737.c: New testcase.

I think this is fixed now, the preprocessed source isn't accepted for me
anymore on trunk.
