tree-ssa-ccp.c (get_default_value): Use SSA_NAME_VALUE rather than SSA_NAME_EQUIV and SET_SSA_NAME_EQUIV.
* tree-ssa-ccp.c (get_default_value): Use SSA_NAME_VALUE rather
than SSA_NAME_EQUIV and SET_SSA_NAME_EQUIV.
(substitute_and_fold): Likewise.
* tree-ssa-dom.c (tree_ssa_dominator_optimize): Remove everything
except invariants from SSA_NAME_VALUE.
(thread_across_edge): Use SSA_NAME_VALUE rather than SSA_NAME_EQUIV
and SET_SSA_NAME_EQUIV.
(restore_vars_to_original_value, record_const_or_copy): Likewise.
(record_equivalences_from_phis, record_const_or_copy_1): Likewise.
(record_equality, cprop_into_successor_phis): Likewise.
(record_equivalences_from_stmt, cprop_operand): Likewise.
(lookup_avail_expr): Likewise.
* tree-ssa-pre.c (fini_pre): Remove everything except invariants
from SSA_NAME_VALUE.
* tree.h (SSA_NAME_EQUIV, SET_SSA_NAME_EQUIV): Kill.
(struct tree_ssa_name): Kill EQUIV field. Remove GGC skip
annotation from the VALUE_HANDLE field.
