(init_expmed): Delete unused variable I.
(enum alg_code): New tag alg_shift.  Document it.
(synth_mult): Delete unused variable N.  Handle new trivial case
first, for T <= 1.  Generalize shifting code to shift whenever a
number is even; use alg_shift for this.  Set best_alg->ops only in
trivial case.  Clean up cost calculation code for the `simple case' at
the end; use shiftadd_cost when appropriate.  Combine declarations of
Q and move to top of function.  Eliminate use of Q in factoring cases.
If we are getting too long a sequence for `struct algorithm' to
record, fail.
(expand_mult): Handle alg_shift instead of alg_add_t_m2 as first
operation.  In RLT emit loop, handle alg_shift; special case LOG == 0
for alg_add_t_m2 and alg_sub_t_m2.
