* genmatch.c (expr::gen_transform): Use fold_buildN_loc
and build_call_expr_loc.
(dt_simplify::gen): Drop non_lvalue for GIMPLE, use
non_lvalue_loc to build it for GENERIC.
(decision_tree::gen_generic): Add location argument to
generic_simplify prototype.
(capture_info): New class.
(capture_info::capture_info): New constructor.
(capture_info::walk_match): New method.
(capture_info::walk_result): New method.
(capture_info::walk_c_expr): New method.
(dt_simplify::gen): Handle preserving side-effects for
GENERIC code generation.
(decision_tree::gen_generic): Do not reject operands
with TREE_SIDE_EFFECTS.
* generic-match.h: New file.
* generic-match-head.c: Include generic-match.h, not gimple-match.h.
* match.pd: Add some constant folding patterns from fold-const.c.
* fold-const.c: Include generic-match.h.
(fold_unary_loc): Dispatch to generic_simplify.
(fold_ternary_loc): Likewise.
(fold_binary_loc): Likewise. Remove patterns now implemented
by generic_simplify.
* gimple-fold.c (replace_stmt_with_simplification): New function.
(fold_stmt_1): Add valueize parameter, dispatch to gimple_simplify.
(no_follow_ssa_edges): New function.
(fold_stmt): New overload with valueization hook. Use
no_follow_ssa_edges for the overload without hook.
(fold_stmt_inplace): Likewise.
* gimple-fold.h (no_follow_ssa_edges): Declare.
