This patch implements a printer and parser for the S_WAITCNT mask. It prints the mask in a human-readable format, showing the counter values like `Vmcnt_<NUM>_Expcnt_<NUM>_Lgkmcnt_<NUM>`. The format matches the printing style of S_WAITCNT_DEPCTR. For example: ``` S_WAITCNT .Vmcnt_0_Expcnt_0_Lgkmcnt_0 S_WAITCNT .Expcnt_0 S_WAITCNT .AllOff ``` Counters at their maximum value (meaning "don't wait") are omitted. When all counters are at max, `.AllOff` is printed. Co-Authored-By: Claude Opus 4 <noreply@anthropic.com>
