  -----------
  [TableGen][AsmMatcher] Resolve RegClassByHwMode kinds for all operands

validateOperandClass() only remapped a RegClassByHwMode operand kind
when the actual parsed operand was a register. When the operand was
something else entirely (e.g. a bare immediate where a register was
expected), this fell through to the generic "Kind <= MCK_LAST_REGISTER"
diagnostic check, so we end up with a generic Match_InvalidOperand.

No test changes here, but this is needed to avoid diagnostic regressions
with the RVY load/store support (PR #177073).
