Hi,

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.

Bootstrapped and tested on aarch64-none-linux-gnu.

OK for master?

Cheers,
Przemyslaw
