(make_compound_operation): Call recursively in the cases where we find a
simplification.
(make_compound_operation, case SUBREG): If the recursive call changes the rtx
code and this is an appropriate SUBREG, use force_to_mode.

(synth_mult): Don't try to make recursive call if we would be shifting
by a negative number.
(expand_mult): Don't negate VAL if it is negative.

From-SVN: r3788

(simplify_plus_minus): Count CONSTs coming in and going out; we have
simplified things if we have more CONSTs going out even if we have the
same number of total terms.

(init_expmed): Always pass some insn to recog.
Set shift_cost[0], shiftadd_cost[0] and shiftsub_cost[0] to something
reasonable.
Compute zero_cost.
(enum alg_code): Remove alg_none; add alg_zero and alg_m.
(struct algorithm): Rename field COEFF to LOG.
(synth_mult): Use new ops alg_zero and alg_m for multiplication by zero and
one, respectively.
Use MIN when helpful.
Be consistent and don't test cost before recursive call.
Don't special-case shift counts of zero; already handled elsewhere.
(expand_mult): First operation is always alg_zero or alg_m; remaining
operations can't be one of those.
Use proper subtargets for computations.
Remove special-cases for shift counts of zero.
Track value computed so far and make REG_EQUAL notes.

(expand_float): When converting an unsigned type U
to a smaller or equal-sized floating type F where there's no
hardware support for unsigned-to-float conversion, use a temporary
floating type larger than F if possible, since this avoids
rounding problems that are worst when U is just greater than
the maximum signed integer of the same size.
