RISC-V: Robostify shuffle index used by vrgather and fix regression
Notice there are some regression FAILs:
FAIL: gcc.target/riscv/rvv/autovec/pr110950.c -O3 -ftree-vectorize scan-assembler-times vslide1up\\.vx 1
FAIL: gcc.target/riscv/rvv/autovec/vls-vlmax/perm-4.c -std=c99 -O3 -ftree-vectorize --param riscv-autovec-preference=fixed-vlmax scan-assembler-times vrgather\\.vv\\tv[0-9]+,\\s*v[0-9]+,\\s*v[0-9]+ 19

pr110950 is not a regression, adapt testcase is enough.
The rest FAILs which is caused by this patch:
https://gcc.gnu.org/git/?p=gcc.git;a=commit;h=d9dd06ad51b7479f09acb88adf404664a1e18b2a
need to be recovered back.
Robostify the gather index to fixe those FAILs.
gcc/ChangeLog:
* config/riscv/riscv-v.cc (get_gather_index_mode): New function.
(shuffle_series_patterns): Robostify shuffle index.
(shuffle_generic_patterns): Ditto.
gcc/testsuite/ChangeLog:
* gcc.target/riscv/rvv/autovec/pr110950.c: Adapt test.
