How would it be deactivated? Through a user option?

The driver would deactivate it (i.e. not pass -lower-esimd to sycl-post-link) in the IR-only output mode, which is only relevant for spec constant processing IIUC. Otherwise it doesn't seem to be influenced by a user-option. I updated the comment to reflect this.

Is the negation correct here?

Adds support for compiling source strings that contain ESIMD kernels only, hence require no device splitting. I'm using a simplified version of the driver logic in
sycl-post-link. The pass pipeline construction helperlowerEsimdConstructsis also copied fromsycl-post-link.
