[PATCH] clang-cl: add more options

[Reid Kleckner]

  LGTM

  You have far more thorough tests than I did.  =D

  The big ones that we will need to implement with custom support are:

  /M(D|Dd|T|Td): Set defines and pick the CRT
  /Fo: Picks an output file or directory
  /showIncludes: used in some build systems for header deps.  This will require actual -cc1 support.

We should alias /Ob0 to -fno-inline.  We can ignore /ObN for N != 0

Not _SLASH_Zc_wchar_t?

I suppose you could toss /showIncludes on here, since we'll need that.
