[clang] -foptimization-record-file= should imply -fsave-optimization-record 

The Clang option -foptimization-record-file= controls which file an
optimization record is output to. Optimization records are output if you
use the Clang option -fsave-optimization-record. If you specify the
first option without the second, you get a warning that the command line
argument was unused. Passing -foptimization-record-file= should imply
-fsave-optimization-record.

This fixes PR33670
