Fix -save-temp when using objc-arc, sanitizer and profiling
Currently, -save-temp will cause ObjCARC optimization to be dropped,
sanitizer pass to run early in the pipeline, and profiling
instrumentation to run twice.
Fix the issue by properly disable all passes in the optimization
pipeline when generating bitcode output and parse some of the Language
Options even when the input is bitcode so the passes can be setup
correctly.
