[PATCH] match.pd: Restrict the X | -X range test to scalars [PR127379]

The X | -X matcher of the range-test patterns has no constant operand,
so vectors reach it and the shift form converts a scalar comparison to
a vector type.  As Andrea Pinski suggested, limit it to integral types;
the other matchers are already scalar through their INTEGER_CST.

Bootstrapped on x86_64-pc-linux-gnu; tree-ssa, vect, dg and dg-torture
tests show no regressions.
