LibC: Make SIZE_MAX be understood by the preprocessor

Browse source 
POSIX mandates that the macros contained in `stdint.h` be suitable for
use by the C preprocessor.

If we write `((size_t)-1)`, the C preprocessor will just skip the cast
and treat the value as `-1`. This means that we end up taking the wrong
branch in an `#if` directive like `#if SIZE_MAX > UINT32_MAX`.

This fixes building the LLVM port on i686.
