fold-const: Handle AND, IOR, XOR with stepped vectors [PR112971].
Found in PR112971 this patch adds folding support for bitwise operations
of const duplicate zero/one vectors with stepped vectors.
On riscv we have the situation that a folding would perpetually continue
without simplifying because e.g. {0, 0, 0, ...} & {7, 6, 5, ...} would
not be folded to {0, 0, 0, ...}.
gcc/ChangeLog:
PR middle-end/112971
* fold-const.cc (simplify_const_binop): New function for binop
simplification of two constant vectors when element-wise
handling is not necessary.
(const_binop): Call new function.
gcc/testsuite/ChangeLog:
* gcc.target/riscv/rvv/autovec/pr112971.c: New test.
