[PATCH] D45835: Add new driver mode for dumping compiler options

The list of features/extensions seems okay; it's information which is already available through a stable interface (specifically, clang -E).  JSON also seems fine as a representation.

Including the language/codegen/etc. options as-is doesn't make sense; we can, and often do, change the internal representation of the option structs.  If the information is useful, we should provide a stable interface.
