arm: Fix MVE's vcmp vector-scalar patterns [PR107987]
This patch surrounds the scalar operand of the MVE vcmp patterns with a vec_duplicate to ensure both operands of the comparision operator have the same (vector) mode. gcc/ChangeLog: PR target/107987 * config/arm/mve.md (mve_vcmp<mve_cmp_op>q_n_<mode>, @mve_vcmp<mve_cmp_op>q_n_f<mode>): Apply vec_duplicate to scalar operand. gcc/testsuite/ChangeLog: * gcc.target/arm/mve/pr107987.c: New test.
