refactor SSA rewriting timevars
This avoids too deep stacks of timevars during incremental
SSA rewrite and basically use TV_TREE_INTO_SSA for all into-SSA
rewrite work and TV_TREE_SSA_INCREMENTAL for update_ssa.
2021-05-06 Richard Biener <rguenther@suse.de>
* timevar.def (TV_TREE_INSERT_PHI_NODES): Remove.
(TV_TREE_SSA_REWRITE_BLOCKS): Likewise.
(TV_TREE_INTO_SSA): New.
* tree-into-ssa.c (insert_phi_nodes): Do not account separately.
(rewrite_blocks): Likewise.
(pass_data_build_ssa): Account to TV_TREE_INTO_SSA.
