Ted Kremenek 653f523664 Revert "Remove sparse text on diagnostic options. These are not really documented anywhere, and they really aren't for normal users." 
I changed my mind.  We should just document these in the man page.

This should be discussed more first.

Daniel Dunbar 0f41eee2a0 Driver: Add support for a new -nostdlibinc option. 
- This disables the system include directories, but not the compiler builtin
   directories. Useful for projects that want to use things like the intrinsic
   headers, but are otherwise freestanding.

 - I'm willing to reconsider the option naming, I also considered providing an
   explicit -builtinc (which would match -nobuiltininc), but this is more
   consistent with existing options.

Daniel Dunbar 10d398f894 Driver: Add a --working-directory option which can be used to cause the compiler 
to operate "as if" in a certain working directory.
 - For now, we just implement this by changing the actual working directory, but
   eventually we would want to handle this transparently. This is useful to
   avoid an extra exec() pair in some situations, and will be something we would
   want to support for more flexibility in using the Clang libraries.

Michael J. Spencer 4992ca4b17 Reorganize predefined macros for all Windows targets. 
This adds an option to set the _MSC_VER macro without
recompiling. This is very useful when testing compatibility
with the Windows SDK and c++stdlib headers.

Daniel Dunbar 092b6fb187 Driver: Add a -stdlib= argument which can be used to select the C++ standard 
library to use.
 - This is currently useful for testing libc++; you can now use 'clang++
   -stdlib=libc++ t.cpp' to compile using it if installed.

 - In the future could also be used to select other standard library choices if
   alternatives become available (for example, to use an alternate C library).

 - Some versions of pod2man aren't happy about the comment after =over=?

 - Some minor grammar fixes.
