tree-optimization/112991 - re-do PR112961 fix

The following does away with the fake edge adding as in the original
PR112961 fix and instead exposes handling of entry PHIs as additional
parameter of the region VN run.

PR tree-optimization/112991
PR tree-optimization/112961
* tree-ssa-sccvn.h (do_rpo_vn): Add skip_entry_phis argument.
* tree-ssa-sccvn.cc (do_rpo_vn): Likewise.
(do_rpo_vn_1): Likewise, merge with auto-processing.
(run_rpo_vn): Adjust.
(pass_fre::execute): Likewise.
* tree-if-conv.cc (tree_if_conversion): Revert last change.
Value-number latch block but disable value-numbering of
entry PHIs.
* tree-ssa-uninit.cc (execute_early_warn_uninitialized): Adjust.

* gcc.dg/torture/pr112991.c: New testcase.
* g++.dg/vect/pr112961.cc: Likewise.

Hmpf, so of course we walk outside of the region with tree_expr_nonnegative_p.
