Argyrios Kyrtzidis d3ba531e64 [frontend] Support passing the optimization record file via the supplemental outputs map
The Swift driver is passing the optimization record file path via the supplementals output, instead of the flag, on certain circumstances.
Enhance the frontend to check supplemental outputs otherwise the record file will not get emitted when using the new swift driver.
