  [Clang] Make Clang driver suggest '-Xclang' for CC1 options passed to the driver

This patch adds an additional check for if an options passed to the
Clang driver could've been intended for the clang compiler. This is
primarily done for the times when a user attempts to pass an option like
`-ast-dump` to the driver instead.
