  Changed paths:
    M mlir/lib/Support/MlirOptMain.cpp

  Log Message:
  -----------
  Avoid creating a ThreadPool in MlirOptMain when `--mlir-disable-threading` option is set

a32300a changed it to create a ThreadPool eagerly so that it gets reused
across buffers, however it also made it so that we create a ThreadPool
early even if we're not gonna use it later because of the command line
option `--mlir-disable-threading` is provided.

Fix #53056
