Description: Fixes #148285 The Issue: Currently, analyzer.py uses a strict positional first = True check when validating macro structures. This strictly forces any uop with records_value == True to be at index 0, which prevents Tier 2 recording uops from safely trailing Tier 1 specializing uops. The Fix: Replaced the boolean first check with a state tracker (valid_recording_pos) in add_macro(). valid_recording_pos starts as True. It remains True if the parsed part is a specializing uop (uop.properties.tier == 1). It ignores CacheEffect and flush parts. It flips to False for any other instruction, properly closing the gate. This safely allows structures like: macro(X) = _SPECIALIZE_X + _RECORD_TOS_TYPE + unused/1 + _X; Issue: gh-148285
