ClangImporter: handle -target-cpu for x86 targets

Browse Source 
`-mcpu` is a deprecated "alias" (unsupported) on x86 targets for
`-mtune`. Unlike `-mcpu`, `-mtune` simply tunes the code for the CPU but
does not prevent execution on other targets. In order to match the
behaviour of `-mcpu` on ARM, we must use both `-march=` and `-mtune=`.
Adjust this behaviour to allow tuning of code for non-Darwin targets.
