In an effort to get libfuzzer working on Windows, we need to make a distinction between what functions require platform specific code (e.g. different code on Windows vs Linux) and what code doesn't. IO functions, for example, tend to be platform specific. This patch separates out some of the functions which will need to have platform specific implementations into different headers, so that we can then provide different implementations for each platform. Aside from that, this patch contains no functional change. It is purely a re-organization. Patch by Marcos Pividori Differential Revision: https://reviews.llvm.org/D27230 llvm-svn: 288264
