re PR rtl-optimization/5263 (a & b & ~a & ~b not optimized)
PR optimization/5263
* simplify-rtx.c (associative_constant_p): Delete.
(simplify_associative_operation): Rewrite to linearize terms, and
attempt to simplify new term against both left and right subterms.
(simplify_binary_operation): Call swap_commutative_operands_p on
op0 and op1, not trueop0 and trueop1. Move the initialization of
trueop0 and trueop1 down to where first needed.
(simplify_relational_operation): Likewise.
* rtlanal.c (commutative_operand_precedence): Also order constant
operands using avoid_constant_pool_reference.
