    [PATCH PR96357][GCC][AArch64]: could not split insn UNSPEC_COND_FSUB with
AArch64 SVE

    Problem is related to that operand 4 (In original pattern
    cond_sub<mode>_any_const) is no longer the same as operand 1, and so
    the pattern doesn't match the split condition.

    Pattern cond_sub<mode>_any_const is being split by this patch into two
    separate patterns:
    * Pattern cond_sub<mode>_relaxed_const now matches const_int
      SVE_RELAXED_GP operand.
    * Pattern cond_sub<mode>_strict_const now matches const_int
      SVE_STRICT_GP operand.
    * Remove aarch64_sve_pred_dominates_p condition from both patterns.

    gcc/ChangeLog:

            PR target/96357
            * config/aarch64/aarch64-sve.md
            (cond_sub<mode>_relaxed_const): Updated and renamed from
            cond_sub<mode>_any_const pattern.
            (cond_sub<mode>_strict_const): New pattern.
