Bug 1275297 - Create Visual Studio project files by default on Windows; r=glandium Now that the VisualStudio backend will no-op if nothing has changed, it should be safe to always run this backend. On first run, backend generation takes ~3.5s on my machine. On subsequent run, it takes ~1.5s. Wall time for a no-op config.status is now ~15.7s. We could like make the Visual Studio backend faster by not writing so many project files. But this would require consolidating libraries in moz.build files. And that's out of scope for this change.

 * The purpose of these structs is described in jemalloc.c, in the comment
 * marked MALLOC_ZONE_T_NOTE.
 *
 * We need access to some structs that come with a specific version of OSX 
 * but can't copy them here because of licensing restrictions (see bug
 * 603655). The structs below are equivalent in that they'll always be
 * compiled to the same representation on all platforms.
 *
 * `void*` and `void (*)()` may not be the same size on weird platforms, but
 * the size of a function pointer shouldn't vary according to its parameters
 * or return type.
 *
 * Apple's version of these structures, complete with member names and
 * comments, is available online at
 *
 * http://www.opensource.apple.com/source/Libc/Libc-763.12/include/malloc/malloc.h
