Match MSVC's handling of commas during macro argument expansion

This allows clang to parse the type_traits header in Visual Studio 2012,
which is included widely in practice.

This is a rework of r163022 by João Matos.  The original patch broke
preprocessing of gtest headers, which this patch addresses.

Patch by Will Wilson!
