[expmed] Properly account for the cost and latency of shift+add ops when synthesizing mults
* expmed.c: (synth_mult): Only assume overlapping
shift with previous steps in alg_sub_t_m2 case.
* gcc.target/aarch64/mult-synth_1.c: New test.
* gcc.target/aarch64/mult-synth_2.c: Likewise.
* gcc.target/aarch64/mult-synth_3.c: Likewise.
* gcc.target/aarch64/mult-synth_4.c: Likewise.
* gcc.target/aarch64/mult-synth_5.c: Likewise.
* gcc.target/aarch64/mult-synth_6.c: Likewise.
