  Log Message:
  -----------
  [SLP]Do not schedule terminate copyable from main op basic block

If the copyable instruction is a terminate instruction from the same
block, as the potential main instruction, such instruction cannot be
copyable and the value list cannot be modeled as instructions with same
(and copyables) opcodes.

Fixes #155183
