* fold-const.h (const_unop): Declare.
(const_binop): Likewise.
* fold-const.c (const_binop): Export overload that expects
a type parameter and dispatches to fold_relational_const as well.
Check both operand kinds for guarding the transforms.
(const_unop): New function, with constant folding from fold_unary_loc.
(fold_unary_loc): Dispatch to const_unop for tcc_constant operand.
Remove constant folding done there from the simplifications.
(fold_binary_loc): Check for constants using CONSTANT_CLASS_P.
(fold_negate_expr): Remove dead code from the REAL_CST case.
Avoid building garbage in the COMPLEX_CST case.
* gimple-match-head.c (gimple_resimplify1): Dispatch to
const_unop.
(gimple_resimplify2): Dispatch to const_binop.
(gimple_simplify): Likewise.
