  [SLP] Fix a check for main/alternate interchanged instruction

If the instruction is checked for matching the main instruction, need to
check if the opcode of the main instruction is compatible with the
operands of the instruction. If they are not, need to check the
alternate instruction and its operands for compatibility and return
alternate instruction as a match.

Fixes #151699
