No targets currently do anything with this information, nor is it presrved
in the bytecode representation. That's coming up next.

When a function takes a variable number of pointer arguments, with a zero
...
pointer marking the end of the list, the zero *must* be cast to the pointer
type. An un-cast zero is a 32-bit int, and at least on x86_64, gcc will
not extend the zero to 64 bits, thus allowing the upper 32 bits to be
random junk.
The new END_WITH_NULL macro may be used to annotate a such a function
so that GCC (version 4 or newer) will detect the use of un-casted zero
at compile time.

SimplifyLibCalls probably has to be audited to make sure it does not make

unsigned, obviously one arm of this is dead.

Basic fix for PR#591; don't convert an fprintf() to an fwrite() if there

is a mismatch in their character type pointers (i.e. fprintf() prints an

sbyte).
