  - Since Printf now records the type and size of each argument, it is
    possible to mix argument types.
  - It is now possible to print the stack pointer. There is only one
    remaining restriction: The `csp` register cannot be printed unless
    it is the current stack pointer. This is because it is modified by

Prevent calls to ReturnValue::Set with pointer-valued types.
  [2nd try, after the previous version broke the build]

Currently, this code will compile:
SomePointer* p = ...;
ReturnValue r = ...;
r.Set(p);

What happens is that ReturnValue::Set has no pointer-ish overloads, but
a bool one, and hence C++ will convert the pointer to a bool and use
the Set(bool) overload. In other words, the example above is equivalent
to: r.Set(p ? true : false); Which probably isn't what the author had
in mind. This change adds a Set(void*) overload whose body forces a
compile error, to prevent this from happening inadvertently. The only
use of this indeed turned out to be an error.

(Said error was fixed/removed in crrev.com/267393002.)

Why was crrev.com/240013004 reverted?
The orginal version compiled fine on gcc (+ MSVC), but not on clang.
There's no clang try-bots, but the ASAN-based buildbots used clang
and hence the build broke. I'm slightly unsure on why, but clang -
unlike those other compilers - eagerly compiled the non-compilable
setter, which predictably broke. Now, the non-compilable setter uses
the same template logic that all other, comparable cases use. I've
tried 'make qc' with both gcc and clang versions.
