I added two flags, `-driver-define` and `-driver-undefine`, to indicate macros that the driver defines. And I moved driver-defined macros from `<command line>` file to `<built-in>` file, like

  # 1 "<built-in>" 3
  #define __llvm__ 1
  #define __clang__ 1
  ...
  # 1 "<command line>" 1
  #define __WHY_NOT_ME__ 1
  #undef __STDC__
  # 1 "<built-in>" 2
  #define __GCC_HAVE_DWARF2_CFI_ASM 1
  ...
