gfx11 chips may, in some conditions, behave incorrectly with S_CLAUSE instructions (hard clauses) containing more than 32 operations (that is, whose arguments exceed 0x1f). However, gfx10 targets will work successfully with clauses of up to length 63. Therefore, define the MaxHardClauseLength property on GCNSubtarget and make it a subtarget feature via tablegen, thus allowing us to specify, both now and in the future, the maximum viable size of clauses on various hardware from the tablegen definition. If MaxHardClauseLength is 0, which is the default, the hardware does not support hard clauses.
