fold-const: Fix up ((1 << x) & y) != 0 folding for vectors [PR99225]
This optimization was written purely with scalar integers in mind,
can work fine even with vectors, but we can't use build_int_cst but
need to use build_one_cst instead.

* fold-const.c (fold_binary_loc) <case NE_EXPR>: In (x & (1 << y)) != 0
to ((x >> y) & 1) != 0 simplifications use build_one_cst instead of
build_int_cst (..., 1). Formatting fixes.
* gcc.c-torture/compile/pr99225.c: New test.
