    arm/97906: Adjust neon_vca patterns to use GLTE instead of GTGE iterator.
    
    gcc/ChangeLog:
            PR target/97906
            * config/arm/iterators.md (NEON_VACMP): Remove.
            * config/arm/neon.md (neon_vca<cmp_op><mode>): Use GLTE instead of GTGE
            iterator.
            (neon_vca<cmp_op><mode>_insn): Likewise.
            (neon_vca<cmp_op_unsp><mode>_insn_unspec): Use NEON_VAGLTE instead of
            NEON_VACMP.
    
    gcc/testsuite/ChangeLog:
            PR target/97906
            * gcc.target/arm/simd/pr97906.c: New test.
