Add per-tune integer, floating-point and vector reassociation widths.
Use 2/2/1 for generic-ooo and 3/2/1 for xt-c9501fdvt, while
keeping other tunes at the default width of one.

* config/riscv/riscv.cc (riscv_tune_param): Add reassociation
widths.
(generic_ooo_tune_info): Set reassociation widths.
(xt_c9501_tune_info): Likewise.
(riscv_reassociation_width): New function.
(TARGET_SCHED_REASSOCIATION_WIDTH): Define.
gcc/testsuite/ChangeLog:
* gcc.target/riscv/reassoc-or-chain.c: New test.

since you added new fields to the structure? For those use whatever the
current defaults are.
