`KImm` operands are (almost) always require special handling.

This patch separates `OPERAND_KIMM32` and `OPERAND_KIMM16` from other operand kinds. In particular, these operands are excluded from `[OPERAND_REG_INLINE_C_FIRST,OPERAND_REG_INLINE_C_LAST]` and from `[OPERAND_SRC_FIRST,OPERAND_SRC_LAST]`.
`opCanUseInlineConstant`, `isSISrcOperand` and `isSISrcInlinableOperand` now return false for `KImm` operands.
