optabs.c (shift_optab_p, [...]): New functions, split out from expand_binop.
gcc/
* optabs.c (shift_optab_p, commutative_optab_p): New functions,
split out from expand_binop.
(avoid_expensive_constant): New function.
(expand_binop_directly): Remove commutative_op argument and
call cummutative_optab_p instead. Do not change op0 or op1
when swapping xop0 and xop1. Apply avoid_expensive_constant
to each argument after potential swapping. Enforce the
canonical order of commutative operands.
(expand_binop): Use shift_optab_p and commutative_optab_p.
Update the calls to expand_binop_directly. Only force constants
into registers when widening an operation. Only swap operands
once a direct expansion has been rejected.
(expand_twoval_binop): Only force constants into registers when
using a direct expansion.
