[ClangImporter] Don't pass API notes options when compiling bitcode. (#10422)

Browse Source 
Avoids a bogus "argument unused" warning, since bitcode compilation
doesn't bother to set up much of a Clang AST context. (-embed-bitcode
compiles in two steps: source -> bitcode, then bitcode -> object
file. This is about the second step.)

Patch by Bob Wilson, who's currently on vacation but wanted this to
get in sooner rather than later.
