Remove VRP threader.
Now that things have stabilized, we can remove the old code.
I have left the hybrid threader in tree-ssa-threadedge, even though the
VRP threader was the only user, because we may need it as an interim
step for DOM threading removal.
Tested on x86-64 Linux.
gcc/ChangeLog:
* tree-pass.h (make_pass_vrp_threader): Remove.
* tree-ssa-threadbackward.c
(back_threader_profitability::profitable_path_p): Remove
ASSERT_EXPR references.
* tree-ssa-threadedge.c (jt_state::register_equivs_stmt): Same.
* tree-vrp.c (vrp_folder::simplify_casted_conds): Same.
(execute_vrp): Same.
(class hybrid_threader): Remove.
(hybrid_threader::hybrid_threader): Remove.
(hybrid_threader::~hybrid_threader): Remove.
(hybrid_threader::before_dom_children): Remove.
(hybrid_threader::after_dom_children): Remove.
(execute_vrp_threader): Remove.
(class pass_vrp_threader): Remove.
(make_pass_vrp_threader): Remove.
