This patch implements a custom printer/parser for the immediate operand of s_wait_alu that prints/parses the decoded counter values. Format: ``` .<counter1>_<value1>_<counter2>_<value2> ``` Example: `s_wait_alu .VaVdst_1_VmVsrc_1` ; Which is equivalent to this: `s_wait_alu 8167` Features: - If a counter is at its maximum value it won't get printed. - The parser will error out if a counter is greater or equal to its max value. - If all counters are disabled we can use 'AllOff'. - For now we also accept numeric values for backwards compatibility with older MIR. Note: This is similar to https://github.com/llvm/llvm-project/pull/96004 but for `s_wait_alu`.
