Clang: Support MSVC style of compiler flags

Clang has MSVC compatible mode which works with MSVC style command line
flags.

When possible use the same flags (-I, -D, -U, etc.) and in other cases
either replace by MSVC analog (for example use /FI instead of -include)
or pass the argument with '/clang:' prefix (requires
https://reviews.llvm.org/D53457).
