[PATCH] clang-cl: Add the /c, /W0 and /W1 options

[Rui Ueyama]

I thought about case-insensitive option handling, and seems we have to
change OptTable to add a new field to indicate whether the option is case
sensitive or not. But this trend to add more fields to OptTable::Info is a
bit worriesome, so I'd like to get you guys' opinion about that.

Adding a new field to the struct is easy. What's I hesitate to do is to
modify every file that includes the tablegen-generated file. Is that
unavoidable? Omitted fields are guaranteed to be initialized by 0 in C++.
If we use this default value, we may not have to modify the files. We have
to silence -Wmissing-field-initializers in some way, though. What do you
think?
