[PATCH 1/9] arm: MVE: Convert vcmp[eq|ne]* in arm_mve.h to use only 's' builtin version

[Christophe Lyon via Gcc-patches]

There is no need to have a signed and an unsigned version of these
builtins. This is similar to what we do for Neon in arm_neon.h.
This mechanical patch enables later cleanup patches.

2021-03-01  Christophe Lyon  <christophe.l...@linaro.org>

        gcc/
        * config/arm/arm_mve.h (__arm_vcmpeq*u*, __arm_vcmpne*u*): Call
        the 's' version of the builtin.
