is more likely than the RHS to be a pointer type in exotic cases,
and it's more tidy to have it return the integer type.

 - Otherwise we unnecessarily pin values to the stack and currently end up
   triggering a backend bug in one case.

 - This loose cooperation with LLVM to implement the ABI is pretty ugly.

the NULL macro, which is defined in a system header.  This also makes the output
a bit nicer, e.g.:

t.c:8:3: warning: null passed to a callee which requires a non-null argument
  func1(NULL, cp2, i1);
  ^     ~~~~

1. When we accept "#garbage" in asm-with-cpp mode, change the token kind
   of the # to unknown so that the preprocessor won't try to process it as
   a real #.  This fixes a crash on the attached example
2. Fix macro definition extents processing to handle #foo at the end of a
   macro to say the definition ends with the foo, not the #.
