Remove find_pdom and find_dom
This removes now useless wrappers around get_immediate_dominator.
2021-11-11 Richard Biener <rguenther@suse.de>
* cfganal.c (find_pdom): Remove.
(control_dependences::find_control_dependence): Remove
special-casing of entry block, call get_immediate_dominator
directly.
* gimple-predicate-analysis.cc (find_pdom): Remove.
(find_dom): Likewise.
(find_control_equiv_block): Call get_immediate_dominator
directly.
(compute_control_dep_chain): Likewise.
(predicate::init_from_phi_def): Likewise.
