The closest thing I've found is '-mllvm <option>' which does set the option correctly, however, this appears to also pass the option to the assembler, which throws me an error that my option is unrecognized.

I cannot reproduce the problem. Running

clang -### -c -save-temps test.c -Xclang -mllvm -Xclang -mfoo -no-integrated-as

shows -mfoo being passed to "clang -cc1", but not to the assembler. Do
open a bug if you have a case where it is being passed.
